"I can't speak for Donald Trump," Eric Fehrnstrom, a Romney senior adviser, said May 25 on CNN. "But I can tell you that Mitt Romney accepts that President Obama was born in the U.S. He doesn't view the place of his birth as an issue in this campaign."

The fundraiser will be at the Trump International Hotel in Las Vegas. Romney will also be joined by former Republican presidential primary rival Newt Gingrich, who will be making his first appearance with Romney since ending his White House bid May 2.

Romney's campaign is also raffling off a meal in June with Trump and the candidate as a fundraising pitch.

Other Stops

Romney is also scheduled to make campaign appearances today in Colorado and Nevada, both crucial swing states in November's election. Romney, 65, is also set to make fundraising stops later in the week throughout California.

Through April 30, Romney raised $100 million, less than half the $222 million for Obama. The incumbent president also has 12 times as much in his campaign account as Romney, $115.2 million compared with $9.2 million.

Romney and Obama honored the legacy of war veterans yesterday with tributes from both sides of the nation. The 2012 campaign marks the first modern presidential election in which neither major party candidate served in the military.

"You are the family and friends of the fallen," Obama said to a military family audience at the Memorial Day Observance at Arlington National Cemetery in Virginia. "For the first time in nine years, Americans aren't fighting and dying in Iraq. We are winding down the war in Afghanistan, and our troops will continue to come home."

With McCain

Romney appeared with Senator John McCain of Arizona at the Veterans Museum and Memorial Center in San Diego.
