Obama hangs out with the 'Racing Presidents'

It's not quite like joining Mount Rushmore, but it'll have to do.

When President Obama visited the annual congressional charity baseball game Thursday at Nationals Park, he hung out with some of the stadium's most famous tenants: The "Racing Presidents" mascots who entertain fans at Nationals' games.

"I challenged them to a race," Obama tweeted out along with a picture of himself and the playful pantheon: George Washington, Thomas Jefferson, William Howard Taft, Theodore Roosevelt and Abraham Lincoln.

As he watched the ball game featuring members of Congress, Obama also schmoozed with lawmakers ahead of big House votes Friday on free trade.
