Larry Klayman, once a hero of conservatives for persistently taking Bill Clinton to court, sued former aides and financial backers of President Bush on Sept. 17 for using the name “Freedom’s Watch” to mount a multimillion dollar campaign in support of the war in Iraq.

In the federal lawsuit, Klayman accuses the group of appropriating a name he has used to promote his own public interest legal work. Klayman, who lives in Miami, said he first used the name Freedom Watch in 2004 on behalf of his nonprofit legal and educational activities and later registered it with the U.S. Patent and Trademark Office.
