CINDY SHEEHAN ARRESTED! I know what you're thinking: She probably wasn't wearing any pants on the subway. But according to CNN, she merely unfolded an anti-war banner...on the grounds of the U.S. Capitol...before the State of the Union address.

WASHINGTON (CNN) -- Cindy Sheehan, the vocal anti-war activist whose son was killed in the Iraq war, was arrested Tuesday night on the grounds of the U.S. Capitol, shortly before President Bush was to deliver his State of the Union address, U.S. Capitol Police said.

A senior House official said Sheehan was seated in the House chamber when she unfolded an anti-war banner and was apprehended. This official said she was taken for questioning for about an hour in a separate area of the House.

"She was arrested within the Capitol complex," a Capitol Hill officer told CNN.

Sheehan had been invited to attend the speech as a guest of Rep. Lynn Woolsey, D-Calif., who has called for a withdrawal for Iraq and supported legislation for a Department of Peace.
