A number of prominent Republicans are vowing to never back Donald Trump
Donald TrumpGOP-led Maricopa County board decries election recount a 'sham' Analysis: Arpaio immigration patrol lawsuit to cost Arizona county at least 2 million Conservatives launch 'anti-cancel culture' advocacy organization MORE even as he closes in on the GOP presidential nomination.
The "Never Trump" ranks include lawmakers, party operatives, pundits and GOP donors — and the movement even sparked a popular hashtag on social media.
They are convinced Trump as standard-bearer would lead the GOP to a devastating defeat in November, costing the party the Senate and potentially the House.
But there are also growing signs many in the GOP establishment are warming to the presumptive nominee. Trump's been endorsed by 14 lawmakers, with others regularly attending Capitol Hill meetings with his staff.
Republican National Committee (RNC) Chairman Reince Priebus has criticized the Never Trump movement as well. "It is essential to victory in November that we all support our candidate," Priebus said at the RNC's spring meeting.
Here's a list of prominent Republicans who won't vote for Trump.
