Romney, Gingrich, Trump will appear together at Las Vegas fundraiser

Newt Gingrich, Donald Trump and Mitt Romney will make an appearance together later this month in Las Vegas.

The three men will appear together at a fundraiser for Romney's presidential bid at Trump Towers on May 29, NBC News reported on Thursday.

In February, Romney received Trump's endorsement during a press conference at the casino. The former Massachusetts governor went on to a commanding win in the state's caucuses, which Trump took partial credit for. Gingrich endorsed Romney shortly after he ended his own presidential bid.

Romney's campaign is also fundraising off a chance to dine with Trump, along with Romney, in New York City. Any supporter who makes a donation will be entered in a raffle to win a trip and dinner with the two men.

The invite reads "I want you. Dine with The Donald and Mitt."

The winner receives: "Airport transportation in the Trump vehicle. Stay at the Trump International Hotel & Tower New York. Tour The Celebrity Apprentice Boardroom. Dine with Donald Trump and Mitt Romney."

President Obama used a celebrity fundraising pitch from George Clooney to raise $15 million for his presidential bid. Obama is now offering donors a chance to dine with him, actress Sarah Jessica Parker and former President Clinton.
