Donald Trump Jabs Jeb Bush on ‘Mommy’ Ad

PELLA, Iowa -- It’s the tweet that tweaked even some of Trump's biggest supporters.

After Jeb Bush posted a video featuring his mother endorsing his campaign, Donald Trump took direct aim at former first lady Barbara Bush.

With temperatures in the teens, 5-long-hours before Donald Trump was scheduled to speak, those most ardent Trump supporters say, in some cases, attacking “mommy” may have crossed a line but others believe while Barbara Bush may be America’s beloved grandmother, she entered the political debate so any tweets or comments are fair game.
