WASHINGTON (AP) — The Supreme Court has agreed to hear an appeal from Secret Service agents who say they should be shielded from a lawsuit over their arrest of a Colorado man who confronted Vice President Dick Cheney.The justices said Monday they will review a federal appeals court decision to allow Steven Howards of Golden, Colo., to pursue his claim that the arrest violated his free speech rights. Howards was detained by Cheney's security detail in 2006 after he told Cheney of his opposition to the war in Iraq.Howards also touched Cheney on the shoulder, then denied doing so under questioning. Appellate judges in Denver said the inconsistency gave the agents reason to arrest Howards. But the judges also said Howards still could sue the agents for violating his rights.
