What's Happening To The GOP Presidential Pledge?

The Republican candidates for president previously agreed to support their party's eventual nominee, whoever that might be. But at last night's town hall in Milwaukee, hosted by CNN, the three remaining contenders cast doubt on that promise.

In September, Donald Trump agreed not to run as a third-party candidate, as long as he was treated "fairly" by party leaders. But last night, Trump said he'd "been treated very unfairly" by "the RNC, the Republican Party, the establishment."

GOP strategist and Here & Now political analyst Paris Dennard joins host Jeremy Hobson for a breakdown of how the candidates' apparent reversals on that vow change the race.
