Senate Minority Leader Mitch McConnell (Ky.) officially backed GOP presumptive presidential nominee Mitt Romney today, just hours after Speaker John Boehner (Ohio) did the same.

“I support [former Massachusetts] Gov. Romney for president of the United States,” McConnell told reporters at his weekly media availability. “We’re all behind him and looking forward to the fall campaign.”

McConnell is just the latest high-profile Republican to endorse Romney after former Sen. Rick Santorum (Pa.) dropped out of the race last week. With Santorum out, no other challenger appears able to overcome the deficit in convention delegates to best Romney for the nomination. Former Speaker Newt Gingrich (Ga.) and Rep. Ron Paul (Texas) remain in the race, however.
