Over the weekend, the multi-millionaire real estate mogul showed up at a raucous Tea Party rally in Boca Raton, Fla., where he deployed a well-known line from his television show while talking about President Obama.
"You're fired," Trump said he might one day like to tell the president.
"We've got a long way to go before we start using that. It's too early, and to be honest, it's too trivial," Trump told the crowd of several thousand. "But I have it in the back of my mind."
Trump plans to ramp up his activity on the speaking circuit, with events already scheduled in crucial early primary states such as Iowa and New Hampshire in June. He has also been generating headlines with a spate of television interviews.
ABC's George Stephanopoulos will sit down one-on-one with Trump Monday, which will air on "Good Morning America" Tuesday morning.
