BOISE, Idaho (AP) — An Idaho man accused of firing an assault rifle at the White House believed he was Jesus and thought President Barack Obama was the Antichrist, according to court documents and those who knew him. At one point, he even suggested to an acquaintance the president was planning to implant computer tracking chips into children.Oscar Ramiro Ortega-Hernandez, 21, was charged Thursday with attempting to assassinate the president or his staff. He is accused of firing nine rounds at the White House last Friday night — one of them cracking a window of the first family's living quarters — when Obama and the first lady were away.
