Anti-war activist Cindy Sheehan was arrested Monday at the Capitol for disorderly conduct, shortly after saying she would run against House Speaker Nancy Pelosi over the California Democrat's refusal to try to impeach President Bush.

Anti-war activist Cindy Sheehan says "Impeachment is not a fringe movement."

Sheehan was taken into custody inside Rep. John Conyers' office, where she had spent an hour imploring him to launch impeachment proceedings against Bush and Vice President Dick Cheney. Conyers, D-Michigan, chairs the House Judiciary Committee, where any impeachment effort would have to begin.[..]

Sheehan and about 200 other protesters had walked to Conyers' office from Arlington National Cemetery. She said Conyers told her there weren't enough votes for impeachment to move forward on the issue.
