Problem:Senate Minority Leader Chuck Schumer has returned an identical letter that Senate Majority Leader Mitch McConnell sent to Harry Reid in 2009 on the Cabinet nomination process, calling on Republicans Monday to comply with the same conditions Republicans demanded when it came to President Obama’s nominees. At the time, McConnell was the minority leader and Democrats controlled the nomination process. 
  
 The New York Democrat read the original letter aloud on the Senate floor and posted the returned one on Twitter a day before President-elect Donald Trump’s nominees are set to begin flooding Capitol Hill for their Senate confirmation hearings. 
  
 Our requests are eminently reasonable, shared by leaders of both parties. I'll return this letter to @SenateMajLdr with the same requests. pic.twitter.com/IMT7ZtJFjV — Chuck Schumer (@SenSchumer) January 9, 2017 
  
 The request says that before the consideration of any time agreements for a confirmation vote, Democrats want the following to be complete for each nominee: FBI background checks, Office of Government Ethics office reviews, financial disclosure statements and committee questionnaires. They are also demanding that each nominee has had a hearing, each nominee is willing to engage in committee staff interviews, each nominee agrees to courtesy visits with lawmakers and each nominee has committed to cooperating with the top Democrat on the relevant committees on requests for transparency and information. 
  
 Schumer’s request comes a few days after the director of the Office of Government Ethics sent a letter to Senate Democrats Saturday in which he expressed concerns with Republicans ramming through the confirmation hearings for Mr. Trump’s nominees. 
  
 “It has left some of the nominees with potentially unknown or unresolved ethics issues shortly before their scheduled hearings,” Walter Shaub Jr. wrote in the letter obtained by CBS News. 
  
 He also noted that some of the president-elect’s nominees have not yet completed the office’s full ethics review. On Saturday, The New York Times reported that some of the Cabinet picks had not yet completed their background checks either. 
  
 This comes as Sen. Jeff Sessions, R-Alabama, prepares to testify at his Senate Judiciary Committee confirmation hearing Tuesday for the role of attorney general. Some of the other nominees who will undergo their confirmation hearings this week include Rex Tillerson for secretary of state, Rep. Mike Pompeo for CIA director and a number of other nominees. 
  
 The Associated Press reported that ethics forms are complete and submitted for Sessions, Tillerson, Defense Secretary nominee Gen. James Mattis and Transportation Secretary nominee Elaine Chao.

 Senate Minority Leader Chuck Schumer offered an explicit warning to Republicans on Monday, saying Democrats are willing to slow down confirmation hearings for Donald Trump's Cabinet until potential nominees finish independent ethics reviews. 
  
 Democrats cannot stop Trump's Cabinet with filibusters, thanks to a rules change they pushed through in 2013, but they can prolong the process for weeks by forcing the GOP to burn through extra time before final floor votes are scheduled. Schumer suggested that such a delay could be in the offing.

 "To spend an extra day or two on each nominee; even if it takes several weeks to get through them all in order to carefully consider their nominations…that’s well worth it," he said. 
  
 Schumer read aloud on the Senate floor from a letter that Majority Leader Mitch McConnell (R-Ky.) sent in February 2009 asking for President Barack Obama's nominees to only receive hearings after the independent Office of Government Ethics and FBI finish vetting their backgrounds. The New York Democrat said the GOP should take the same approach to Trump's would-be Cabinet — several members of which have yet to finish their OGE ethics reviews. 
  
 And shortly afterward, the Democratic leader sent a copy of the letter back to McConnell, after scratching out the original recipients and scrawling "Mitch" instead. 
  
 "I only ask respectfully that the Republican majority follow the same set of standards they had in 2009 when the shoe was on the other foot," Schumer said. "Especially because these nominees raise particular concerns." 
  
 Notably, McConnell sent his 2009 letter, which one source told POLITICO did not receive a response at the time from then-Senate Majority Leader Harry Reid (D-Nev.), weeks after the Senate confirmed seven senior Obama nominees on his first day in office. The Kentucky Republican has called for a similar pace for Trump's Cabinet, telling reporters at Trump Tower on Monday that he wants to see upwards of a half-dozen nominees confirmed on Inauguration Day, and on Sunday urged Democrats to "grow up." 
  
 Nine members of Trump's prospective Cabinet are set to receive confirmation hearings this week, with OGE ethics reviews still unreleased for four of them — Education Secretary pick Betsy DeVos, Commerce Secretary pick Wilbur Ross, Housing and Urban Development pick Ben Carson, and retired Gen. John Kelly, the president-elect's Department of Homeland Security pick.

Solution:
In 2009, then-Senate Minority Leader Mitch McConnell sent then-Senate Majority Leader Harry Reid a letter asking that President Obama's Cabinet nominees not be granted Senate confirmation hearings until the Office of Government Ethics and the FBI had vetted them and other ethical review steps had been taken. On Monday, current Senate Minority Leader Chuck Schumer sent the same letter back to McConnell, after writing "Mitch" in the recipient field and crossing out Reid, the original recipient—CBS has a picture. Schumer also read the letter out loud on the Senate floor, as a warning to Republicans that, now that the Democrats are the underdogs, they're willing to take the same steps Republicans did years ago to slow down confirmation hearings, Politico reports. The request comes days after the Office of Government Ethics sent a letter to Senate Democrats airing concerns that Republicans are pushing through the confirmation process—nine of Trump's Cabinet nominees have confirmation hearings scheduled this week, even though the OGE has not released ethics reviews yet for four of them. "To spend an extra day or two on each nominee; even if it takes several weeks to get through them all in order to carefully consider their nominations ... that’s well worth it," Schumer said on the Senate floor Monday. "I only ask respectfully that the Republican majority follow the same set of standards they had in 2009 when the shoe was on the other foot. Especially because these nominees raise particular concerns." McConnell on Sunday pooh-poohed the OGE's concerns.
