Anti-war activist Cindy Sheehan is running for U.S. Congress as an Independent and she hopes to topple the current Speaker of the House in the process.

According to the Houston Chronicle, Sheehan, a Californian, announced she will challenge Nancy Pelosi if the lawmaker has not moved to impeach Bush and Cheney by July 23–the day she plans to arrive in Washington after her 13-day caravan to the nation’s capitol.

“My campaign is going to happen, because we know she is not going to put impeachment on the table,” Sheehan said.

A spokesman for Pelosi said her “focus is on winning the war in Iraq.”
