RICHMOND, Va. (AP) — A federal appeals court has affirmed a Maryland man’s convictions for sending threatening letters to then-President George W. Bush.

A three-judge panel of the 4th U.S. Circuit Court of Appeals in Richmond on Friday unanimously rejected Scott Rendelman’s claims that the letters did not amount to genuine threats and that the indictment did not properly allege violations of the law.

Rendelman, 55, mailed the letters to the U.S. Marshals Service in 2005 and 2006, while he was in prison for extortion. In the first, he vowed to kill “government scumbags” and the president after his release from prison. In the second, he said he would kill the president and all White House employees.
