Whatever insults the billionaire businessman dished out to rivals Ted Cruz and Marco Rubio at Thursday night's GOP debate, he got back in spades.
Rubio came out swinging and managed to fluster the front-runner with a few choice blows – including one about how Trump would be stuck selling watches had he not gotten an inheritance.
Later, Rubio repeatedly told viewers to Google "Trump Polish workers" so that voters could read up on a since-settled lawsuit alleging that the real estate mogul knowingly employed and abused illegal Polish immigrants to demolish an old building to make way for Trump Tower.
But the most buzzed-about zinger of the night came from Cruz and had to do with the former Trump University – a series of seminars promising to teach students how to make money in real estate. Following up on an earlier reference made by Rubio, Cruz pointed out that Trump is due to appear in court as a witness in a case charging him and the former "university" with fraud.
"I want you to think that if this man is the nominee, having the Republican nominee on the stand in court being cross-examined about whether he committed fraud," Cruz said. "You don't think the mainstream media won't go crazy on that?"
As the election progresses and Trump racks up more and more delegates, he's increasingly facing attacks from prominent GOPers who fear for the future of their party should the businessman make his way to the White House. The latest onslaught is from former Massachusetts Gov. Mitt Romney, who in recent days has repeatedly questioned Trump's failure to release his tax returns.
Trump said during the debate that he would like to release the returns but he can't because he's being audited by the IRS, a claim Romney was quick to pounce on. "@realDonaldTrump taxes for last 4+ years are still being audited," Romney tweeted Thursday. "There are more #bombshells or he would release them."
Former GOP presidential hopeful and South Carolina Sen. Lindsey Graham also ripped into Trump at the Washington Press Club Foundation Dinner in the Capitol basement Thursday, calling his ex-rival a "nut job," "a loser as a person" and "ill-suited to be president."
Graham added, however, that he would still back Trump if he won the GOP nomination. "I've got a ticket on the Titanic. So I am like on the team that bought a ticket on the Titanic, after we saw the movie. This is what happens if you nominate Trump," he said.
But, he warned GOP voters, "You can't have it both ways. You can't nominate a nut job and lose, and expect it doesn't have consequences."
