The White House is standing by its rapper.

Lonnie Rashid Lynn Jr., who raps under the name Common, will appear Wednesday night as scheduled at a celebration of American poetry and prose at the White House, despite criticism from Sarah Palin and other conservative political figures about  some of his lines, including a song praising a man convicted for killing a police officer and this 2007 rhyme about former Republican President George W. Bush: “Burn a Bush ’cause for peace he no push no button/Killing over oil and grease/no weapons of destruction.”
