Could Donald Trump Ruin Mitt Romney's Campaign?

Could a major endorsement and fundraiser from Donald Trump actually hurt Mitt Romney's campaign more than help it? INSIDE EDITION has the scoop.

As Mitt Romney is on his way to a Donald Trump fundraiser in Las Vegas, he's flying into a storm of controversy.  

George Will on ABC This Week said, "What voter is going to vote for him because he is seen with Donald Trump? The cost of appearing with this bloviating ignoramus is obvious, it seems to me."

That's right - conservative commentator George Will called Trump a "bloviating ignoramus."

Trump struck back, tweeting, "George Will may be the dumbest (and most overrated) political commentator of all time. If the Republicans listen to him, they will lose."

Why the controversy?

Trump is once again questioning President Obama's birthplace. He was back at it Tuesday morning, calling in to CNBC from his Vegas hotel room at 4:30 a.m.

Trump said, "There's a whole lot of things, you know. His mother was never in the hospital. They don't even know which hospital it was. His grandmother said he was born in Kenya. Now look, it all wouldn't matter except, if you're born in a foreign country you're not allowed to be president."

Now a chorus of other political commentators, some of them Republican, are questioning Romney's decision to campaign with Trump.

Peggy Noonan on CBS This Morning said, "My view is that the Romney campaign made a mistake. This is a good time for him to differentiate himself from the stranger aspects of the Republican race."

The fundraiser at the Trump International Hotel is expected to raise $2 million.

Romney said, "I don't agree with everyone who supports me, and my guess is that they all don't agree with everything I believe in. But I need to get 50.1% or more, and I'm appreciative to have the help of a lot of good people."

A spokesperson for the Obama campaign said, "Once again, Mitt Romney is failing the moral leadership test. Instead of rejecting Donald Trump's 'birther' conspiracy theories and divisive attacks, he's endorsing them by campaigning and fundraising with him."

A statement was released from Romney campaign headquarters said, "Governor Romney has said repeatedly that he believes president Obama was born in the United States. The democrats can talk about Donald Trump all they want---Mitt Romney is going to talk about jobs and how we can get our economy moving again."
