opinion: Justice Rehnquist
  delivered the opinion of the Court.
  Petitioners assaulted an undercover United States Secret Service agent with a loaded pistol, in an attempt to rob him of $1,800 of Government “flash money” that the agent was using to buy counterfeit currency from them. They were convicted of violating 18 U. S. C. § 2114, which proscribes the assault and robbery of any custodian of “mail matter or of any money or other property of the United States.” The United States Court of Appeals for the Eleventh Circuit affirmed petitioners’ convictions, over their contention that § 2114 is limited to crimes involving the Postal Service. 718 F. 2d 1528 (1983). We granted certiorari, 466 U. S. 926 (1984), to resolve a split in the Circuits concerning the reach of § 2114, and we affirm.
  Agent K. David Holmes of the United States Secret Service posed as someone interested in purchasing counterfeit currency. He met petitioners Jose and Francisco Garcia in a park in Miami, Fla. Petitioners agreed to sell Holmes a large quantity of counterfeit currency, and asked that he show them the genuine currency he intended to give in exchange. He “flashed” the $1,800 of money to which he had been entrusted by the United States, and they showed him a sample of their wares — a counterfeit $50 bill.
  Wrangling over the terms of the agreement began, and Jose Garcia leapt in front of Holmes brandishing a semiautomatic pistol. He pointed the pistol at Holmes, assumed a combat stance, chambered a round into the pistol, and demanded the money. While Holmes slowly raised his hands over his head, three Secret Service agents who had been watching from afar raced to the scene on foot. Jose Garcia dropped the pistol and surrendered, but Francisco Garcia seized the money belonging to the United States and fled. The agents arrested Jose Garcia on the spot, and pursued and later arrested Francisco Garcia as well.
  Petitioners were convicted in a jury trial of violating 18 U. S. C. §2114 by assaulting a lawful custodian of Government money, Agent Holmes, with intent to “rob, steal, or purloin” the money. That section states in full:
  “Whoever assaults any person having lawful charge, control, or custody of any mail matter or of any money or other property of the United States, with intent to rob, steal, or purloin such mail matter, money, or other property of the United States, or robs any such person of mail matter, or of any money, or other property of the United States, shall for the first offense, be imprisoned not more than ten years; and if in effecting or attempting to effect such robbery he wounds the person having custody of such mail, money, or other property of the United States, or puts his life in jeopardy by the use of a dangerous weapon, or for a subsequent offense, shall be imprisoned twenty-five years.”
  Both petitioners were sentenced to the 25-year prison term mandated by § 2114 when the assault puts the custodian’s life in jeopardy by use of a dangerous weapon. On appeal the Court of Appeals for the Eleventh Circuit affirmed the judgments of conviction. The only issue before us on certiorari is whether the language “any money, or other property of the United States” in § 2114 includes the $1,800 belonging to the United States and entrusted to Agent Holmes as “flash money” in this case.
  Section 2114 prohibits the assault with intent to rob of “any person having lawful charge, control or custody of any mail matter or of any money or other property of the United States . . . .” (emphasis supplied). Petitioners contend that notwithstanding the reach of this language, Congress intended that only the robbery of “postal” money or property was to be covered by the statute.
  The enacted language of the statute is contrary to petitioners’ argument. The language protects custodians of any mail matter, custodians of any United States money, and, in a catchall phrase, custodians of any other United States property. As in our recent case of Lewis v. United States, 445 U. S. 55 (1980), “[n]othing on the face of the statute suggests a congressional intent to limit its coverage to persons [employed by the Postal Service].” Id., at 60.
  The three classes of property protected by § 2114 are each separated by the conjunction “or.” Canons of construction indicate that terms connected in the disjunctive in this manner be given separate meanings. See FCC v. Pacifica Foundation, 438 U. S. 726, 739-740 (1978). In Reiter v. Sonotone Corp., 442 U. S. 330 (1979), we refused to ignore the statutory meaning which would be presumed from similar disjunctive language, stating that the use of the term “or” indicates an intent to give the nouns their separate, normal meanings. Id., at 339. In our case, Congress separated “mail matter,” “money,” and “other property” from one another by use of a disjunctive, and we think this means that the word “money” must be given its ordinary, separate meaning; it does not mean “postal money” or “money in the custody of postal employees.”
  Petitioners contend that the language of the statute is ambiguous, and in support of this contention offer what seems to us a rather labyrinthine explanation of the statutory language. Petitioners first claim that the conjunction “or” cannot properly be read to totally separate the three types of property listed in the prohibition; for if the word “or” indeed strictly separates the three types of property, the statute would proscribe assaults on custodians of any “money,” whether or not it was money belonging to the United States, because the term “money” would not be modified or restricted by the term “of the United States” which follows the word “property.” Thus Congress would have enacted a law, say petitioners, proscribing assaults on custodians of money by whomever owned, and “Congress would then have enacted a Federal robbery statute without any jurisdictional basis.” Reply Brief for Petitioners 8. Because Congress could not have intended this absurd result, petitioners contend, there is an ambiguity in the statutory language. This contention, however, totally ignores the word “other” which follows “money” and shows that the money referred to, like the property referred to, is money belonging to the United States.
  Petitioners then develop their argument by invoking the principle of ejusdem generis to resolve the ambiguity which their analysis creates. Under that principle, of course, where general words follow an enumeration of specific terms, the general words are read to apply only to other items like those specifically enumerated. See Harrison v. PPG Industries, Inc., 446 U. S. 578, 588 (1980). Petitioners thus urge that “mail matter” is a specific term, and therefore the general terms “money” and “other property” which follow it must be read in the specific, restricted postal context. They conclude that “money” was intended to mean “postal money” and “other property of the United States” was intended to mean “other postal property.”
  We said in Harrison that “‘“the rule of ejusdem generis, while firmly established, is only an instrumentality for ascertaining the correct meaning of words when there is uncertainty.””’ Ibid., quoting United States v. Powell, 423 U. S. 87, 91 (1975), in turn quoting Gooch v. United States, 297 U. S. 124, 128 (1936). We are not persuaded that petitioners’ analysis of the statutory language creates any ambiguity in the plain meaning of the words, and even if it did we do not think that the particular language here lends itself to the application of the ejusdem generis rule. We have previously noted that the terms in question are made separate and distinct from one another by Congress’ use of the disjunctive; in addition, the term “mail matter” is no more specific a term — and is probably less specific — than “money.”
  Notwithstanding petitioners’ argument to the contrary, we are satisfied that the statutory language with which we deal has a plain and unambiguous meaning. While we now turn to the legislative history as an additional tool of analysis, we do so with the recognition that only the most extraordinary showing of contrary intentions from those data would justify a limitation on the “plain meaning” of the statutory language. When we find the terms of a statute unambiguous, judicial inquiry is complete, except in “‘rare and exceptional circumstances,’” TVA v. Hill, 437 U. S. 153, 187, n. 33 (1978), quoting Crooks v. Harrelson, 282 U. S. 55, 60 (1930).
  Section 2114 had its genesis as a law to protect mail carriers from assault and robbery of mail matter. The forerunner to §2114 was 18 U. S. C. §320 (1934 ed., Supp. V). It proscribed assault and robbery of “any person having lawful charge, control, or custody of any mail matter.” Section 320 had been placed in Chapter 8 of Title 18 of the United States Code. Chapter 8 was entitled “Offenses Against Postal Service.” In 1935, however, the 74th Congress amended § 320 by appending after the term “mail matter” the clause “or of any money or other property of the United States.” Section 320 as amended retained its place in Chapter 8 of Title 18 until 1948, when it was transferred to Chapter 103, which is entitled “Robbery and Burglary” and contains all of the federal statutes covering those crimes. Act of June 25, 1948, ch. 645, 62 Stat.. 797. Section 320 was then renumbered as §2114; with the exception of minor particulars the text of the statute has remained unchanged since the 1935 amendment.
  Petitioners contend that the 1935 amendment to § 320 was not intended to expand the reach of that statute beyond postal crimes. In support of this they rely on some short colloquies from the House floor which they describe as “snippets.”
  In surveying legislative history we have repeatedly stated that the authoritative source for finding the Legislature’s intent lies in the Committee Reports on the bill, which “represent] the considered and collective understanding of those Congressmen involved in drafting and studying proposed legislation.” Zuber v. Allen, 396 U. S. 168, 186 (1969). We have eschewed reliance on the passing comments of one Member, Weinberger v. Rossi, 456 U. S. 25, 35 (1982), and casual statements from the floor debates. United States v. O’Brien, 391 U. S. 367, 385 (1968); Consumer Product Safety Comm’n v. GTE Sylvania, Inc., 447 U. S. 102, 108 (1980). In O’Brien, supra, at 385, we stated that Committee Reports are “more authoritative” than comments from the floor, and we expressed a similar preference in Zuber, supra, at 187.
  The Committee Reports on this bill show no intent on the part of the 74th Congress to limit the amended §320 to less than the normal reach of its words. The House Report on the bill to amend § 320 is entitled “SAFEGUARDING CUSTODIANS OF GOVERNMENT MONEYS AND PROPERTY” and states that “[t]he purpose of the pending bill is to bring, within the provisions of the Penal Code the crime of robbing or attempting to rob custodians of Government moneys.” H. R. Rep. No. 582, 74th Cong., 1st Sess., 1 (1935). The Senate Report on the 1935 amendment is entitled “PROVIDING FOR PUNISHMENT FOR THE CRIME OF ROBBING OR ATTEMPTING TO ROB CUSTODIANS OF GOVERNMENT MONEYS OR PROPERTY,” and the Senate Report states the purpose of the bill exactly like the House Report. S. Rep. No. 1440, 74th Cong., 1st Sess., 1 (1935). Nowhere do the Committee Reports state that the amended statute required a “postal nexus” or was limited to postal crimes.
  Petitioners make a good deal of the fact that both Reports contain the letter from the Postmaster General, requesting enactment of the bill. That official’s letter, however, says nothing about limiting the broad language of the bill to postal crimes, but instead speaks simply of “custodian[s] of Government funds,” not of Government “mail.” H. R. Rep. No. 582, supra, at 1; S. Rep. No. 1440, supra, at 1. In two places the Postmaster General’s letter states that the bill was designed to punish the crime of “robbing or attempting to rob custodians of Government moneys.” Ibid. Thus the Committee Reports show that the Postmaster, and the two Committees responsible for the legislation, gave no evidence of their belief that the statute was limited to postal crimes.
  Petitioners rely heavily on the statement of Representative Dobbins, whom the dissent identifies as the floor manager, made on the floor of the House of Representatives on May 24, 1935. Representative Dobbins stated:
  “The only purpose of the pending bill is to extend the protection of the present law to property of the United States in the custody of its postal officials. . . . [L]et me say there are many custodians of postal stations who have a great amount of money in their custody but little mail____” 79 Cong. Rec. 8205 (1935).
  We find a number of flaws in petitioners’ argument that Representative Dobbins’ statement is clear proof of Congress’ intent. First, this snippet quotes Representative Dobbins out of context. The above-quoted statement was made in response to an objection from another Member concerning the mandatory 25-year penalty in the proposed statute. As one in favor of the bill, Representative Dobbins’ attempt to limit the scope of the statute is best read in light of this objection. See ibid. To permit such colloquies to alter the clear language of the statute undermines the intent of Congress. Regan v. Wald, 468 U. S. 222, 237 (1984). See Russello v. United States, 464 U. S. 16 (1983). Isolated statements such as Representative Dobbins’ are “not impressive legislative history.” Zuber, supra, at 187. If they were, a statement of Representative Wolcott earlier in the same colloquy to the effect that “[tjhis bill is confined to assaults on Federal law-enforcement officers,” 79 Cong. Rec., at 8205, would seem to counterbalance the import of Representative Dobbins’ statement. Thus petitioners would lose even if we were to adopt some type of reverse parol evidence rule, where oral statements were elevated above enacted language in determining the meaning of the statute.
  We think probably the strongest argument that may be made for limitation on the coverage of § 2114, although petitioners do not themselves make it as such, is that set forth in the opinion of the Court of Appeals for the Second Circuit in United States v. Reid, 517 F. 2d 953 (1975), and amplified by our dissenting colleagues today. This argument is certainly not without persuasive power, and it would perhaps be controlling if there were substantial ambiguity in the language Congress had enacted. But there is nó such ambiguity. We are not willing to narrow the plain meaning of even a criminal statute on the basis of a gestalt judgment as to what Congress probably intended.
  As a final argument petitioners assert that they are vindicated by the Solicitor General’s earlier stipulation in United States v. Hanahan, 442 F. 2d 649 (CA7 1971), vacated and remanded, 414 U. S. 807 (1973). In that case we were faced with the identical issue presented here, but we vacated and remanded in light of the Solicitor General’s concession that §2114 only applied to postal crimes. The Solicitor General now states that his concession in Hanahan was unwarranted. As we noted in NLRB v. Iron Workers, 434 U. S. 335, 351 (1978), a governmental agency “is not disqualified from changing its mind” concerning the construction of a statute. See also Barrett v. United States, 423 U. S. 212, 222 (1976). Moreover, private agreements between litigants, especially those disowned, cannot relieve this Court of performance of its judicial function. It is our responsibility to interpret the intent of Congress in enacting §2114, irrespective of petitioners’ or respondent’s prior or present views. “[T]he proper administration of the criminal law cannot be left merely to the stipulation of [the] parties.” Young v. United States, 315 U. S. 257, 259 (1942). We agree that the Solicitor General’s prior concession was ill-advised, but it does not control this case.
  Petitioners seek to clip §2114 despite its plain terms, but “[t]he short answer is that Congress did not write the statute that way.” Russello, 464 U. S., at 23. Instead, Congress selected language that penalized assaults or robberies of anyone who is a custodian of “any money or other property of the United States.” It is beyond question that by using a pistol in an effort to rob Agent Holmes, petitioners fell squarely within the prohibitions of the statute.
  The judgment of the Court of Appeals is therefore affirmed.
  It is so ordered.
  See United States v. Reid, 517 F. 2d 953 (CA2 1975); United States v. Rivera, 513 F. 2d 519 (CA2), cert. denied, 423 U. S. 948 (1975); United States v. Fernandez, 497 F. 2d 730 (CA9 1974), cert. denied, 420 U. S. 990 (1975).
  Petitioners were also convicted of other crimes. See 718 F. 2d 1528 (1983).
  As Justice Jackson stated:
  “Resort to legislative history is only justified where the face of the Act is inescapably ambiguous, and then I think we should not go beyond Committee reports, which presumably are well considered and carefully prepared. . . . [T]o select casual statements from floor debates, not always distinguished for candor or accuracy, as a basis for making up our minds what law Congress intended to enact is to substitute ourselves for the Congress in one of its important functions.” Schwegmann Bros. v. Calvert Distillers Corp., 341 U. S. 384, 395-396 (1951) (concurring).
  Despite the Solicitor General’s view, Government prosecutors had relied on § 2114 outside of the postal context. See, e. g., United States v. O’Neil, 436 F. 2d 571 (CA9 1970) (Customs Service employee); United States v. Sherman, 421 F. 2d 198 (CA4) (military money custodian), cert. denied, 398 U. S. 914 (1970); Peek v. United States, 321 F. 2d 934 (CA9 1963) (same).
  We disagree with petitioners’ assertion that §2114 as we have read it does not fit well with other federal statutes, especially §2112. The statutes are related but not duplicitous. Section 2112 prohibits only consummated robberies of any person — whether lawful custodian or not— possessing any type of personal property of the United States. The difference between § 2112 and § 2114 is that the latter is specifically directed to authorized custodians, and protects them against assaults accompanying both attempted and completed robberies. Thus the statutes complement each other.
