A Kansas lawyer who was arrested last year after holding an anti-war sign at a political rally where President George W. Bush spoke is suing the leader, claiming his constitutional rights were violated, according to a media report. Dennis Hawver, who has run as a Republican and a Libertarian in unsuccessful bids for Congress and the Kansas governor's office, filed the federal lawsuit Monday against Bush and the Kansas Republican Party, the Topeka Capital-Journal reported. The lawsuit alleges that Hawver's Nov. 5, 2006, arrest at the Kansas rally was a "politically motivated violation of my civil and constitutional rights." Hawver said he was arrested after holding up a sign that said "Stop War" during Bush's speech. He said a Kansas Republican Party representative instructed two men to arrest and remove him from the gathering.
