Police Officer Blasts 'Hateful' Anti-Trump Protesters

Did Donald Trump go too far with his retweet of an unflattering picture of Ted Cruz's wife?

The war of words between the Republican presidential rivals is growing uglier by the day and their wives, Melania Trump and Heidi Cruz, are being dragged into the mudslinging.

The latest exchange was sparked when an anti-Trump super PAC launched an ad that shows Melania posing nude during a 2000 GQ photo shoot. It suggested that voters should turn out for Cruz or Melania could be the next first lady.

Trump quickly responded with a threat:

Cruz has maintained that the super PAC is not affiliated with his campaign.

Trump, however, wasn't buying it and he then retweeted someone's meme which mocked Cruz's wife's appearance.

Cruz responded, chastising Trump for attacking a woman:

The Outnumbered hosts weighed in this afternoon, with Andrea Tantaros lamenting the ugliness of these attacks.

"We've devolved into a discussion of which woman is hotter and we're comparing women's looks. Ask any woman: it's a pretty ugly place," she said, calling on the Cruz and Trump "to get back to the issues."

Rachel Campos-Duffy, wife of Rep. Sean Duffy (R-WI), said that she thinks spouses should be off-limits in campaigns.

She added that Trump's attacks may be a signal to Republicans about how he will go after Bill and Hillary Clinton if he becomes the nominee.
