Sheehanista is escorted by security personnel out of the House of Representatives chamber before the State of the Union address by President Bush on Capitol Hill in Washington January 31, 2006.

WASHINGTON (CNN) — Peace activist Cindy Sheehan was arrested Tuesday in the House gallery after refusing to cover up a T-shirt bearing an anti-war slogan before President Bush’s State of the Union address.
“She was asked to cover it up. She did not,” said Sgt. Kimberly Schneider, U.S. Capitol Police spokeswoman, adding that Sheehan was arrested for unlawful conduct, a misdemeanor.
The charge carries a maximum penalty of one year in jail, Schneider said.
Schneider said shortly after the State of the Union speech that Sheehan was still being held but should be “out sometime tonight.”
Sheehan was an invited guest of Rep. Lynn Woolsey, D-California, who has called for a withdrawal of troops in Iraq.
