Hillary Clinton's Former IT Staffer to Plead the Fifth in Court Deposition in Email Lawsuit Bryan Pagliano's lawyers say he won't talk to prosecutors about Clinton's email.

 -- Bryan Pagliano, the former U.S. State Department staffer who worked on Hillary Clinton’s private email server, will invoke his Fifth Amendment rights at a June 6 deposition in D.C. District Court, his lawyers say.

Pagliano’s Monday deposition is set in a lawsuit over public records brought by the conservative group Judicial Watch, regarding the operation of Clinton’s server and the employment status of one of her top aides. “Mr. Pagliano is a nonparty caught up in a lawsuit with an undisputed political agenda,” his lawyers said in a court filing, obtained by ABC News.

Judicial Watch asked that Pagliano’s deposition be recorded on video, to which Pagliano’s lawyers said there was no “proper purpose” --because he won’t answer questions anyway – and left Pagliano vulnerable to “considerable risk of abuse.”

Pagliano also declined to answer questions from the Benghazi Select Committee last September. He has, however, agreed to cooperate with the FBI's investigation into Clinton's email server and has been granted immunity as part of that process.

The State Department said early last month it could not locate the majority of Pagliano’s emails from the time he served as Clinton’s senior information technology staffer during her tenure as U.S. secretary of state.
