Here's Donald Trump's Memorial Day Message to Americans

'I Am Terrible at History': Watch People Fail Watters' Memorial Day Quiz

Donald Trump won the Republican presidential nomination fair and square and the GOP needs to unite behind him, Senate Majority Leader Mitch McConnell said on "Fox and Friends" this morning.

"Donald Trump won this thing the good old-fashioned way: He got more votes than anybody else," McConnell said. "I think we ought to respect the wishes of the Republican voters. They've chosen him as the candidate."

He explained that resisting Trump or pushing for a third-party candidate would just increase the odds that Hillary Clinton is elected president.

"From a policy point of view, why would anybody in the conservative world want to do anything to elect Hillary Clinton?" McConnell asked.

"Given the alternative, I don't don't have any trouble at all supporting Donald Trump, and I hope everybody right of center does."

Watch more above, and be sure to tune in to "The Kelly File" tonight at 9:00 p.m. ET to see Megyn Kelly's can't-miss interview with McConnell.
