Robert L. Woodson Jr., 39, a campaign adviser to President Bush and a former chief of staff at the Department of Housing and Urban Development, was killed Feb. 8 when his car flipped over in Silver Spring, Montgomery County police reported.

Mr. Woodson, who lived in Adelphi, was senior vice president of the National Center for Neighborhood Enterprise and the son of the center's president, Robert L. Woodson. The younger Woodson was taking his half brother, Jamal Woodson, to buy a CD when his Ford Mustang hit a patch of black ice on Layhill Road south of Middlevale Lane and overturned, police said.

Jamal Woodson was treated at Suburban Hospital.

Robert Woodson, who was known as Rob, was senior policy adviser on housing and community development issues for George W. Bush's presidential campaign. He was transition director for HUD before being named deputy chief of staff at the agency.

He resigned as chief of staff to rejoin his father's organization last year. He had begun there as an intern after graduating from the University of Delaware and was its former director of public policy. The nonprofit center's programs include training of leaders in low-income communities. It also provides technical assistance to help solve problems of housing and other development needs.

Mr. Woodson, a native of Philadelphia, also had worked on Capitol Hill as a staff assistant with the House subcommittee on children, youth and families and as a budget analyst with the House Budget Committee. He also was chief of staff for then-Rep. Bob Inglis (R-S.C.) and legislative assistant to Sen. Kay Bailey Hutchison (R-Texas).

At the National Center, Mr. Woodson worked to implement changes to the Housing Act that put into law resident management and homeownership in public housing. He also directed a "What Works and Why" program that identified successful grass-roots organizations.

In addition to his father, of Silver Spring, and half brother, of Philadelphia, survivors include his wife, Michelle Akar Woodson, and two children, Ariana Michelle Woodson and Robert L. Woodson III, all of Adelphi; his mother, Joyce Sandra Woodson of Wilmington, Del., and his stepmother, Ellen Woodson of Silver Spring; a brother, Ralph Woodson of Washington; and a half sister, Tanya Woodson of Silver Spring.
