The employee who helped set up and manage Hillary Clinton's private email server for her work as secretary of state no longer works at the State Department, a department spokesman said on Thursday. Bryan Pagliano is cooperating with the Federal Bureau of Investigation's criminal inquiry into the email setup in exchange for immunity from prosecution by the U.S. Department of Justice. The investigation has clouded Hillary Clinton's campaign to become the Democratic Party's candidate in the November presidential election. Clinton has apologized for the arrangement but says she did nothing wrong and that she believes the government will vindicate her. Pagliano's lawyer did not respond to requests for comment. A Clinton spokesman said the campaign is pleased that Pagliano is cooperating, but declined to respond to questions.
