WASHINGTON - Lawyers for a man charged with trying to assassinate President Barack Obama by shooting at the White House are trying to get his statements to authorities thrown out.

Lawyers for Oscar Ramiro Ortega-Hernandez said in a court document Wednesday the statements were coerced. The attorneys say Ortega-Hernandez was handcuffed to a chair for two hours after his arrest and they've been unable to find a document where he agreed to waive his rights and talk to authorities.

Lawyers said Ortega-Hernandez told FBI and Secret Service agents that his car was stolen at gunpoint and he didn't do the drive-by shooting. He also told them he never reported the car stolen.

No one was injured in the 2011 shooting. Obama was away at the time.

Ortega-Hernandez has pleaded not guilty.
