Conyers is facing numerous allegations of sexual assault and harassment from former female employees.
"I am retiring today", Conyers, 88, told a Detroit radio station, as he became the first to step down among four serving USA lawmakers facing sexual misconduct allegations.
Arnold Reed, attorney for Rep. John Conyers, holds up an image of Conyers and Marion Brown, one of the two women accusing the congressman of inappropriate behavior, as he addresses the media in Detroit on December 1. He endorsed his son John Conyers III to succeed him.
Speaking from an unnamed hospital where he reportedly was being treated for stress-related complications, the longest-serving member of Congress maintained that the allegations against him "are not true", and that he could not explain their origin.
Reed has said Conyers' health would be the paramount consideration in whether he decides to step down from his House seat. Conyers has denied any wrongdoing. Grubbs is the cousin of another accuser, Marion Brown, who reached a confidential settlement with Conyers over sexual harassment allegations, but broke the confidentiality agreement to speak publicly last week.
In the affidavit, Grubbs said Brown told her, "That SOB just wanted me to have sex with him".
The House Ethics Committee is reviewing allegations of harassment against John Conyers.
'The allegations against congressman Conyers as we have learned more since Sunday are serious, disappointing and very credible, ' said Pelosi, a California representative who notably did not call for Conyers to go during a Sunday appearance on NBC's 'Meet the Press'.
Pressure had been mounting for Conyers, who was hospitalized in MI late last month, to resign. Bloom previously represented Hollywood executive Weinstein, who is accused of sexual misconduct by a number of women.
Buzzfeed News reported on November 20 that Conyers had settled a complaint in 2015 from a woman who alleged she was sacked from his Washington staff because she rejected his sexual advances.
Rep. John Conyers' attorney is expected to make an announcement later this morning.
Grubbs' affidavit says that she worked for Conyers in various roles from approximately 2001 to about 2013. "We're calling for due process for every citizen, which also includes Congressman John Conyers by the same body which is supposed to uphold and defend due process". Conyers has denied all the allegations, and on Tuesday, wrote the accusations off as "politics".
Conyers has already stepped down from his leadership position as ranking member on the House Judiciary Committee late last month.
