 A former State Department staffer who worked on Hillary Rodham Clinton’s private e-mail server tried this week to fend off a subpoena to testify before Congress, saying he would assert his constitutional right not to answer questions to avoid incriminating himself. 
  
 The move by Bryan Pagliano, who had worked on Clinton’s 2008 presidential campaign before setting up the server in her New York home in 2009, came in a Monday letter from his lawyer to the House panel investigating the 2012 attack on the U.S. consulate in Benghazi, Libya. 
  
 The letter cited the ongoing FBI inquiry into the security of Clinton’s e-mail system, and it quoted a Supreme Court ruling in which justices described the Fifth Amendment as protecting “innocent men . . . �?who otherwise might be ensnared by ambiguous circumstances.’ ” 
  
 The FBI is investigating whether Clinton’s system — in which she exclusively used private e-mail for her work as secretary of state — may have jeopardized sensitive national security information. 
  
 Thousands of e-mails that have been released by the State Department as part of a public records lawsuit show Clinton herself writing at least six e-mails containing information that has since been deemed classified. Large portions of those e-mails were redacted before their release, on the argument that their publication could harm national security.

 “While we understand that Mr. Pagliano’s response to this subpoena may be controversial in the current political environment, we hope that the members of the Select Committee will respect our client’s right to invoke the protections of the Constitution,” his attorney, Mark MacDougall, wrote. 
  
 Two other Senate committees have contacted Pagliano in the past week, according to a copy of the letter, which was obtained by The Washington Post. The requests came from the Senate Judiciary Committee and the Homeland Security Committee, according to people familiar with the requests. 
  
 The Senate Judiciary Committee confirmed Wednesday that it sought to ask Pagliano about his work for Clinton. 
  
 “In response to questions . . . Mr. Pagliano’s legal counsel told the committee yesterday that he would plead the Fifth to any and all questions if he were compelled to testify,” a spokesperson for committee Chairman Charles E. Grassley (R-Iowa) said in a statement. 
  
 Rep. Trey Gowdy (R-S.C.), the chairman of the House Benghazi committee, had subpoenaed the computer staffer Aug. 11 and ordered that he appear for questioning before the committee Sept. 10. Gowdy also demanded that Pagliano provide documents related to the servers or systems controlled or owned by Clinton from 2009 to 2013. 
  
 Pagliano, who worked in the State Department’s information-technology department from May 2009 until February 2013, left the agency when Clinton departed as secretary. He now works for a technology contractor that provides some services to the State Department. 
  
 The committee’s ranking Democrat, Rep. Elijah Cummings (D-Md.), complained yesterday that Gowdy unilaterally issued the subpoena. He said the subpoena of a low-level aide is one of several signs that Gowdy is using the committee for the political purpose of trying to smear a Democratic presidential candidate.

Caption Clinton has come under fire for using a private email address during her time as secretary of state. The emails are being screened and released in batches. Here are some things we’ve learned from them. Top-secret information in e-mails Democratic presidential candidate Hillary Clinton has previously stated that classified information never traveled across her private server. However, the State Department has acknowledged that "top secret" information was in seven email chains sent or received by her. Richard Drew/AP Buy Photo Wait 1 second to continue. 
  
 “Although multiple legal experts agree there is no evidence of criminal activity, it is certainly understandable that this witness’s attorneys advised him to assert his Fifth Amendment rights, especially given the onslaught of wild and unsubstantiated accusations by Republican presidential candidates, members of Congress and others based on false leaks about the investigation,” Cummings said. “Their insatiable desire to derail Secretary Clinton’s presidential campaign at all costs has real consequences for any serious congressional effort.” 
  
 MacDougall declined to comment late Wednesday evening. ||||| A former Hillary Clinton staffer who helped set up the former secretary of state’s private email server has vowed to plead the Fifth and refuse to answer questions after a congressional committee subpoenaed him, msnbc confirmed late Wednesday. 
  
 Bryan Pagliano, who worked for Clinton during her 2008 presidential campaign and at the State Department, has been identified in digital records as the person who set up her email server in 2009. 
  
 The House Select Committee on Benghazi, which is investigating Clinton’s emails, subpoenaed Pagliano last month to testify. But his lawyer said Monday that the IT specialist would refuse to answer questions, asserting his constitutional right against self-incrimination, The Washington Post first reported Wednesday. 
  
 “While we understand that Mr. Pagliano’s response to this subpoena may be controversial in the current political environment, we hope that the members of the Select Committee will respect our client’s right,” attorney Mark MacDougall wrote in a letter obtained by msnbc to Benghazi Committee Chairman Rep. Trey Gowdy. 
  
 The letter cites the fact the FBI is already investigating the security of Clinton’s email server, and notes that Pagliano had been contacted in the past week by two separate Senate committees also looking into the matter.

 Pagliano was IT director for Clinton’s 2008 presidential campaign before serving as special advisor to the Department of State under Clinton from May 2009 through February 2013, according to his LinkedIn page. 
  
 Pagliano’s move will likely pour fuel on partisan fire over Clinton’s email server, with opponents sure to cite it as evidence that Clinton and her team are stonewalling investigators. 
  
 It’s unclear what, if anything, Pagliano could be held accountable for. Refusing to testify could be an attempt to avoid accidentally perjuring himself under oath. 
  
 Clinton’s campaign said late Wednesday that they had hoped Pagliano would answer the committee’s questions and encouraged him to do so. “His decision is both understandable and yet also disappointing to us,” a campaign aide said in a statement. 
  
 “We have been confident from the beginning that Hillary Clinton’s use of a personal email was allowed and that she did not send or receive anything marked classified, facts confirmed by the State Department and the Inspector General. She has made every effort to answer questions and be as helpful as possible, and has encouraged her aides, current and former, to do the same, including Bryan Pagliano. In fact, two of those aides are due to testify this week, and she is eager to testify in a public hearing in October,” the aide added. 
  
 “Although multiple legal experts agree there is no evidence of criminal activity, it is certainly understandable that this witness’ attorneys advised him to assert his Fifth Amendment rights,” said the Benghazi Committee’s top Democrat, Rep. Elijah Cummings. 
  
 Cummings went on to suggest that Republicans’ asserts that Clinton had committed a crime could have lead Pagliano’s attorney to advise against testimony. “Their insatiable desire to derail Secretary Clinton’s presidential campaign at all costs has real consequences for any serious congressional effort,” Cummings said. 
  
 In a memo shared with Democratic members of the committee, the committee staff point to numerous examples of Republican presidential candidates claiming Clinton had committed a crime. They also note that one can plead the Fifth even if there is no criminal investigation. |||||
Solution:
Bryan Pagliano's is not a household name, but he soon might be the most well-known IT guy in the nation. He is a former State Department staffer who helped set up Hillary Clinton's private email server, and at least three congressional committees want him to testify, reports the Washington Post. However, it looks like Pagliano isn't interested in talking. His lawyer sent a letter this week to a House panel investigating Benghazi declaring that his client would take the Fifth if compelled to appear. The letter also notes that the Senate Judiciary and Homeland Security panels have made similar requests of him. “While we understand that Mr. Pagliano’s response to this subpoena may be controversial in the current political environment, we hope that the members of the Select Committee will respect our client’s right,” attorney Mark MacDougall writes in the letter obtained by MSNBC. The network notes that it's unclear what legal trouble Pagliano fears, but that his position "will likely pour fuel on the partisan fire over Clinton's email server." In the latest revelation, it turns out that Clinton wrote six emails herself that were later deemed to be classified, notes the Post. (Here are eight highlights from the latest release.)
