The top leader in the Iowa Senate says he’s resigning after a video posted on a liberal news website purportedly showed him kissing a statehouse lobbyist. Senate Republicans released a statement Monday announcing that Senate Majority Leader Bill Dix was resigning effectively at 2 p.m. from his leadership post and as a state senator. Republicans in the GOP-controlled chamber plan to elect a new majority leader on Wednesday.

The incident caps a swift response from Republicans in the chamber after the liberal website Iowa Starting Line published video and photos showing Dix and a woman together at a bar. The video allegedly showing the married Republican kissing a statehouse lobbyist. The website says the incident was recorded March 1.

Governor Kim Reynolds told reporters Monday she was “disappointed” about the allegation against Senate Majority Leader Bill Dix.
