A top official at the Chamber of Commerce, the group that's a reliable supporter of the GOP and its candidates, is calling on Donald TrumpDonald John TrumpKoch-backed group launches six-figure ad buy against Heitkamp Anti-abortion Dem wins primary fight Lipinski holds slim lead in tough Illinois primary fight MORE to resign and cede the nomination to Mike PenceMichael (Mike) Richard PenceJohn Oliver says his parody Pence rabbit book has sold out Charlotte Pence responds to John Oliver's rabbit book spoof: ‘I’m all for it’ No constitutional authority for the feds to confiscate guns without due process MORE in light of his lewd comments leaked Friday.  

"There is no GOP nominee for President in 2016. Fundamentally offensive & unqualified," Rob Engstrom, the national political director and senior vice president at the Chamber, tweeted late Friday night. 
"Trump should step down immediately tonight, yielding to Governor Pence as the GOP Nominee."
Republicans have broadly condemned Trump since the release of 2005 audio from a hot mic while appearing on NBC's "Access Hollywood."
During the audio, released by The Washington Post, Trump said that women let you "do anything" if you are "a star." He goes on to talk about trying to seduce a married woman and speaks lewdly about pursuing other women.
"You know I'm automatically attracted to beautiful — I just start kissing them. It's like a magnet. Just kiss. I don't even wait. And when you're a star they let you do it. You can do anything," he said in the audio. 
"Grab them by the p----,” Trump says. "You can do anything."
