HRC seemed to employ a "prevent defense" strategy tonight. Donald Trump went for it, and won. #debate2016

When asked if that meant he now supports Trump again, Calley tweeted is was "just an observation."

DETROIT (AP) - Michigan Lt. Gov. Brian Calley and U.S. Rep. Fred Upton have called on Donald Trump to drop out of the presidential race after his vulgar 2005 comments about women.
Calley is the first Michigan Republican leader Saturday to renounce support for Trump, The Detroit News reported.
Calley says in a statement: "The latest revelations about Donald Trump and his past make it impossible for me to maintain support of him."
He called on Trump to step aside for a replacement.
Upton, the senior Republican in Michigan's House delegation, says the revelation "only confirms" his decision not to endorse Trump.
He urged Trump to step aside for the good of the country.
Gov. Rick Snyder, who has not endorsed Trump, had no comment on the controversy, spokeswoman Anna Heaton said.
