A physician who treated dying Ebola patients in Liberia flew in to JFK on Thursday night — and stayed at an airport hotel, a source told The Post. Colin Bucks, a clinical assistant professor at Stanford University’s medical school, arrived on a Royal Moroccan Air flight, sources said. He spent the night at the Hilton Garden Inn in Jamaica, Queens, where Centers for Disease Control workers also stay, according to a source. On Friday, he was cleared to travel home to Northern California, where he will “be monitored by CDC there,” the source said.
