MADISON, Wis. (AP) _ Former Georgia congresswoman Cynthia McKinney stopped in Wisconsin as part of her campaign for the Green
Party nomination for president.

Among about 50 people attending a McKinney news conference yesterday in Madison, the state capital, was Kevin Barrett. He is a
former University of Wisconsin lecturer who taught that the U.S.
government was behind the September 11th terrorist attacks.

Supporters held signs that said "9/11 Truth Now'' and "Impeach.''

McKinney is known for suggesting that President Bush ignored warnings of the attacks because friends in the defense industry would profit from a war. She has hosted numerous panels on September 11th conspiracy theories, which Barrett champions.

One of her final acts in Congress was to introduce a bill to impeach Bush. She said he misled Congress into approving the war in Iraq and violated the law by secretly spying on citizens.

McKinney served five terms in Congress as a Democrat representing a district east of Atlanta. Now, she says she is pushing a true peace agenda and advocating "radical common sense.''

McKinney left Congress after losing the Democratic primary in 2006 to Hank Johnson.
