WASHINGTON (AP) — Former First Lady Laura Bush is joining an advisory board to help raise money to build the Smithsonian Institution's planned black history museum.

Bush will join Brown University President Ruth Simmons and Target Corp. CEO Gregg Steinhafel as new members of the National Museum of African American History and Culture advisory board.

Others who have been helping to raise private funds to build the museum include Oprah Winfrey, Quincy Jones and Citigroup chairman Richard Parsons.

The new appointments were announced Jan. 25.

The museum is scheduled for completion in 2015 on the National Mall near the Washington Monument.

Congress has pledged to provide half of the museum's $500 million cost, with private fundraising to cover the rest.
