White House Press Secretary Tony Snow announced that Bush, who had previously refused invitations from the nation's oldest civil rights organization, will speak at the conference Thursday, the Washington Post reported Wednesday.
"I think the president wants to make the argument that he has had a career that reflects a strong commitment to civil rights," Snow said.
"Yes, they have political disagreements," Snow said, but "Bruce Gordon ... and the president have good relations."
The appearance will prevent the president from becoming the first since Warren G. Harding to avoid speaking to the organization for his entire term. Previous presidents that the NAACP had been critical of, including Richard Nixon and Ronald Reagan, had spoken at the organization's annual convention.
