President Barack Obama, Brad Pitt, Angelina Jolie confab in Oval Office

WASHINGTON (AP) -- - President Barack Obama might be powerful and well-known, but the White House got some real star power Wednesday: Brad Pitt and Angelina Jolie stopped by for a chat with the chief executive.
 
The uber-famous Hollywood pair were spotted in the Oval Office by photographers waiting outside for the president to take off for a trip to Chicago.
 
The White House confirmed Pitt and Jolie were in town to screen Jolie's movie about Bosnian war crimes at the Holocaust museum, and dropped by so the president could talk with Jolie about her work on preventing mass atrocities and combating sexual violence against women.
 
Pitt was seen sporting a cane, which he's been using following a skiing injury.
