The Missouri House speaker says most Republicans in his chamber have signed a petition calling for a special session during which lawmakers could consider impeaching Republican Gov. Eric Greitens.
House Speaker Todd Richardson did not provide specific numbers Thursday but said "well over a majority" of Republicans are on board. He also anticipates overwhelming support from Democrats.
Three-quarters of each chamber of the Legislature must sign off on a special session.
Lawmakers are to halt work May 18 on their regular session.
Greitens is to go to trial May 14 on a felony indictment accusing him of taking a compromising, unauthorized photo of a woman with whom he had an affair. He also faces a felony charge related to his use of a charity donor list for his gubernatorial campaign.
