A mentally ill homeless man has been charged with threatening to shoot President Bush.

Secret Service agents were called to the psychiatric unit of St. Joseph's Hospital, where Timothy Wade Pinkston, 47, had been taken on an involuntary commitment order.

Pinkston told hospital staff that he planned to go to Washington and shoot the president. When Secret Service agents arrived to interview him, he repeated the threat, saying he doesn't like the president's foreign policy or his handling of the war in Iraq, according to an affidavit filed by the Secret Service in U.S. District Court.

Pinkston was charged Friday with threatening the president, a federal crime.

According to the affidavit, he was previously charged with threatening the president in 1991, and also sent threatening letters to the governor of Georgia.
