Ted Cruz says if Donald Trump sues him as threatened over a campaign ad, the lawsuit would be dismissed as frivolous.

Cruz lashed out at Trump at a news conference Wednesday in South Carolina, three days before the state’s primary.

Cruz says the ad, which includes footage of Trump declaring his support for abortion rights, can’t be defamatory because it includes comments Trump himself made on national TV. Trump has since said his position has changed and he is anti-abortion.

Speaking directly to Trump, Cruz says. “you have been threatening frivolous lawsuits for your entire adult life. Even in the annals of frivolous lawsuits, this takes the cake.”
