WASHINGTON — Rep. John Conyers, who’s facing sexual harassment allegations, has been hospitalized for stress, a political consultant said, and his lawyers was expected to make a statement this afternoon.

Sam Riddle said Thursday he spoke to Conyers’ wife, Monica Conyers. Riddle says he doesn’t know why the Democrat congressman was hospitalized or his condition.

He declined to name the hospital.

The top Democrat in the U.S. House says Michigan Rep. John Conyers should resign in the face of allegations of sexual misconduct.

Minority Leader Nancy Pelosi told reporters Thursday that the accusations against Conyers are “serious, disappointing and very credible. It’s very sad.”

Pelosi told reporters “zero tolerance means consequences – for everyone no matter how great the legacy it’s not licensed to harass or discriminate. In fact it makes it even more disappointing.”

The 88-year-old Conyers has been under pressure after multiple women who’ve worked for him accused him of sexual harassment.

He denies the allegations, and his lawyer says he won’t resign. Conyers is the longest-serving member of the U.S. House.

One woman, Marion Brown, told NBC’s “Today” show on Thursday that she was propositioned for sex multiple times over more than a decade before she was fired.

She says she stayed on the job because she needed to support her family and found the work rewarding.

Arnold Reed, an attorney for Conyers, tells The Associated Press that Conyers is innocent and has no plans to resign. Reed adds that anyone making inappropriate touching or other claims against the Detroit Democrat should be prepared to back them up.

Conyers, who has served in Congress since 1964, returned to Detroit on Tuesday, although the House of Representatives is still in session.
