An African man is due to appear in Florida federal court Wednesday on charges that he plotted to send uranium to Iran, the Associated Press reported.
Patrick Campbell, 33, from Sierra Leon, is charged with attempting to violate the U.S. embargo against Iran, according to the AP. He has not entered a plea.
Campbell was arrested last month after authorities say he agreed to sell 1,000 tons of yellowcake uranium -- which can be used to make nuclear weapons -- to a buyer who was actually an undercover Homeland Security agent, The New York Times reported.
According to the Times, Campbell was seized at New York's John F. Kennedy International Airport on his way to meet the buyer in Florida with what authorities said were uranium samples hidden in shoes packed in his luggage.
