MSNBC's Nicolle Wallace reveals how she 'triggered' Fox News this week

Former Republican Nicolle Wallace, who hosts "Deadline White House" on MSNBC, revealed that she triggered some folks at Fox News this week when she confessed she can't understand someone like Nikki Haley.

Haley announced she was endorsing Donald Trump on Wednesday, sending shockwaves through the anti-Trump wing of the GOP that persisted in supporting her despite dropping out months ago. The move came after Trump spent months attacking Haley's family, including her husband, who was serving overseas in the military.
