A subset of the Marine Corps band struck up one of Mitt Romney's walkout songs while President Obama was greeting visitors at the White House Independence Day celebration.
A White House pool report said the band struck up Rodney Atkins's "It's America," and described it as an "awkward moment."
Military families were treated to an evening of barbecue, fireworks and a concert featuring the Marine Band and country star Brad Paisley.
In his remarks welcoming the attendees, Obama thanked them for their service to the country
"It is always such an honor for us to spend this holiday with members of our military and your extraordinary families," said the president. "So as your commander in chief — but also as an American — I wanted to invite all of you over to say one thing: Thank you."

Here's some color from POTUS' visits with the troops.
After his remarks, POTUS and FLOTUS made a bee-lime for the crowd where he began to shake hands and sign autographs, and continued to do so until 6:49 when he left the South Lawn, walked around to the Oval Office and then towards the playground set where several children were playing.
Some fathers were hoisting there small children, whose faces were painted in red-white-and-blue designs, onto their shoulders to see the president.
Pool was then ushered back to the press area at the White House.
One awkward moment: A New York Times photographer in the pool mentioned that shortly after Obama ended his remarks and was shaking hands, the a subset of the Marine Corps band played one of Mitt Romney's main walkout songs, Rod Atkins' "It's America."
The best patriotic outfit pool spotted was a woman standing in line to get an autograph who eventually gave up and walked away empty-handed. The woman was wearing a tank-top dress completely made out of small red, white, and blue balloons -- no joke.
