A former spokesman for Rep. John Conyers, D-Mich., suggested Tuesday it was no "big deal" for staff to find the House's longest serving member wearing only his underwear in his Washington office.

"He changes clothes in his office. Most of us have walked in on him changing his clothes ... and have seen him in his underwear," Bob Weiner told congressional reporters outside Conyers' base in the Rayburn House Office Building. "Big deal!"

Weiner added that Conyers, who has been accused of harassment by three former employees, had a closet in his workspace, according to MSNBC's Kasie Hunt.

One of two women to allege Conyers harassed her on the record, Melanie Sloan, told the Washington Post of one occasion in which she was summoned to Conyers' office while she was the House Judiciary Committee's minority counsel from 1995 to 1998.

When she opened the door, the congressman was standing there in his underwear, Sloan said.

Weiner served as press secretary and communications director for the House Oversight Committee and National Security Subcommittee, then chaired by Conyers, from 1990 to 1995.

Conyers on Sunday stepped down as ranking member of the House Judiciary Committee pending a House Ethics Committee investigation into Sloan's claims, as well as other complaints made by multiple other women accusing Conyers of sexual misconduct.

One complaint was settled in 2015, whereas another lawsuit was abandoned in 2017 after a judge refused the woman's request to keep her matter sealed.

Deanna Maher, the second woman to go on the record with allegations against Conyers, told the Detroit News on Tuesday that Conyers sexually harassed her three times during her years working with the congressman from 1997 to 2005.
