Rev. Jerry Falwell, a prominent conservative televangelist, was hospitalized in "gravely serious" condition after being found unconscious in his office Tuesday, a Liberty University executive said. Ron Godwin, the executive vice president of Falwell's Liberty University, said Falwell was found unresponsive around 10:45 a.m. and taken to Lynchburg General Hospital. Godwin said he was not sure what caused the collapse, but "he has a history of heart challenges." "I had breakfast with him, and he was fine at breakfast," Godwin said. "He went to his office, I went to mine and they found him unresponsive." Godwin said Falwell was receiving emergency care. A hospital spokeswoman said she had "no information to release at this time" on Falwell.
