Sen. Lindsey Graham (R-S.C.) reportedly spent the weekend urging big-money Republican donors to support presumptive nominee Donald Trump. It's a pretty shocking turnaround for a guy who was once the loudest—and sometimes only—critic of Trump in the GOP presidential field. Before caving in to Trump's now-inevitable victory in the GOP primaries, Graham insulted Trump, apologized to Muslims for him, called for him to be kicked out of the GOP, and endorsed two of his rivals in last-ditch attempts to block Trump from being nominated.
