Hollywood celebrities Roseanne Barr and Martin Sheen have endorsed anti-war activist Cindy Sheehan in her longshot bid to win Rep. Nancy Pelosi’s (D-Calif.) seat.
Other celebrities who have endorsed Sheehan include actor Sean Penn and singers Melissa Etheridge and Willie Nelson.
Sheehan, who is running as an independent, has challenged the Speaker to a debate, but Pelosi has not agreed to one.
Sheehan told The Hill in 2007 that attracting celebrity backing would be a key facet of her campaign.
Pelosi has received political donations this cycle from actor Robin Williams, writer Aaron Sorkin, producer Steve Bing and golf course architect Robert Trent Jones.
