Gainer, who formerly served as chief of the Capitol Police, is the longest-serving sergeant at arms since World War II.
The retirement announcement comes one day after Reid asked Gainer to investigate allegations by Sen. Dianne Feinstein (D-Calif.) that the CIA had searched computers of the Senate Intelligence Committee, which she leads. In letters to CIA director John Brennan and Attorney General Eric Holder, Reid said he had asked Gainer to conduct a forensic investigation of the committee’s computer to find out how copies of a CIA report had wound up on them.
Reid on Thursday did not say when Gainer would be leaving, but said his replacement will be Drew Willison, the deputy sergeant at arms. Michael Stenger, a former longtime member of the Secret Service, will serve as deputy, Reid said.
The sergeant at arms "enforces rules of the Senate, provides services to senators in their Washington D.C. and state offices and maintains security in the Capitol and Senate office buildings," according to the Senate's website.
