Rep. John Conyers (D., Mich.) is expected to announce on Tuesday that he will not seek reelection to Congress in 2018 after former employees' accusations of sexual harassment against him became public.
The notice was leaked by a family member of Conyers who is expecting to run for the seat, the New York Times reports.
Top Republicans and Democrats have called on Conyers, the longest-serving member of the House of Representatives, to resign after lurid accusations of sexual misconduct emerged, the Times noted.
Speaker Paul D. Ryan and Representative Nancy Pelosi, the Democratic leader, have each said Mr. Conyers should resign after a woman who settled a sexual harassment claim against him said on television that the congressman had "violated" her body, repeatedly propositioned her for sex, and asked her to touch his genitals. Other former staff members have since come forward to say he harassed them or behaved inappropriately.
Michigan State Sen. Ian Conyers (D.), the congressman's great-nephew, said Conyers would not resign immediately but would serve out the remainder of his current term.
"He is not resigning. He is going to retire," Ian Conyers said. "His doctor advised him that the rigor of another campaign would be too much for him just in terms of his health."
The elder Conyers is expected to make the announcement in an interview with a local radio show.
"People are ready to support our dean and to support our family as we continue to fight, as we have for leading up to a century, for people from Southeast Michigan," Ian Conyers said.
Some of Ian Conyers' detailed predictions in the original Times report were different from Conyers' announcement on Tuesday. The congressman announced he was immediately resigning from Congress and endorsed his son, John Conyers III, to run for his seat.
