"I am retiring today", Conyers, 88, told a Detroit radio station, as he became the first to step down among four serving U.S. lawmakers facing sexual misconduct allegations.
On Monday, yet another allegation was lodged against Conyers, when a woman who said she worked for the congressman for more than a decade, Elisa Grubbs, said he slid his hand up her skirt and rubbed her thighs while she was sitting next to him in the front row of a church.
Conyers' lawyer confirmed that the retirement is effective immediately.
He is endorsing his son, John Conyers III, to replace him in Congress.
The move comes amid numerous calls, including from Democratic leadership, for Conyers to step down in light of allegations of sexual misconduct and harassment against him.
The news comes after Conyers' great-nephew, 29-year old MI state Senator Ian Conyers, told CBS News' Jonathan Blakely he would be running for the elder Conyers' seat. "This too shall pass", he said, calling in from a local hospital.
As allegations of sexual misconduct continue to swirl around him, several of Conyers' congressional colleagues encouraged him to resign.More news: Marlins have Giancarlo Stanton trade worked out with Giants, Cardinals

The congressman, who took his MI seat in the House in 1965, has already stepped aside as the top Democrat on the Judiciary Committee amid swirling allegations of sexual improprieties.
"When Rep. Conyers inappropriately touched me like this", said Grubbs, as reported by the paper, "my eyes would pop out and I would be stunned in disbelief".
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.
The rally at the Hartford Memorial Baptist Church on James Couzens in Detroit comes as some members of the media and Congress have called for Conyers to resign. "My client Marion Brown asks only for an acknowledgment and apology".
Rep. Sherry Gay-Dagnogo (D-Detroit), Pastor Charles G. Adams, Pastor Christian Adams, the Rev. Wendell Anthony, the Rev. Charles Williams, the National Action Network, a delegation of 13th Congressional District Leaders and others will be at the event. "I hope my retirement will be viewed in the larger perspective of my record of service as I enter a new chapter", the statement from Conyers read.
"This goes with the issue of politics".
"Whatever they are they are not accurate, they are not true, and I think that they are something that I can't explain where they came from", said Rep. Conyers. The RealClearPolitics average has him up by 1.5 points in the polls, and many-but not all-signs point to his winning the seat. I'm a co-sponsor on all of them.
