"The last few months have been incredibly hard for me, for my family, for my team, for my friends and for many, many people", Greitens said in a speech on Tuesday, announcing that he will resign as of Friday at 5 p.m.
Greitens, who had consistently refused to heed calls within his own party for his resignation, announced hours later that he would give up the governor's seat.
"The last few months have been incredibly hard for me, for my family, for my team, for my friends and for many, many people".
Greitens's mistress, who has not been publicly identified, claimed that he took a photo of her partially nude, bound and blindfolded, without her permission, and threatened to release the photo if the affair became public.
The 44-year-old governor made the announcement almost 17 months after taking the oath of the office with a pledge to root out "corrupt career politicians".
The governor also was indicted on invasion-of-privacy charges in February in St. Louis for allegedly taking an unauthorized and compromising photo of a woman during an extramarital affair in 2015, before he was elected. Jackson County Prosecutor Jean Peters Baker is leading that probe. Her spokeswoman said the agreement was in regard to a second St. Louis charge, a felony data-tampering case involving Greitens' alleged use of a charity donor list for political fundraising.More news: Liverpool forward, Mohammed Salah ruled out of world cup
A former Greitens campaign adviser also told a state House investigative committee that the campaign had considered soliciting donations from foreign nationals, according to the newspaper.
Some Republicans were anxious that Greitens' issues could cause problems for GOP Senate candidate and state Attorney General Josh Hawley in his challenge of Democratic U.S. Sen.
House Speaker Todd Richardson said Wednesday that he didn't know whether the House still has the power or desire to enforce the subpoena now that Greitens is resigning. Greitens says the allegations are "ridiculous" and resists calls to resign.
"The time has come though, to tend to those who have been wounded, and to care for those who need us most", he said.
Greitens resigns amid a sexual misconduct scandal and allegations of misusing a charity list.

A complaint also remains pending at the Missouri Ethics Commission alleging Greitens filed a false campaign report a year ago about the source of the charity donor list.
The woman alleges that after Greitens took the photograph, he said: "You're not going to mention my name". "I don't believe the market was treating the state's constitutional crisis surrounding the impeachment process as any sort of a credit risk".
Roe said Greitens had been prepared for a two-stage fight.
Greitens had faced trial in early May on the invasion of privacy charge. Greitens had hoped to be acquitted, which Roe said would have allowed him to mount a full defense against the potential House impeachment proceedings.
