US President Donald Trump says he wants to stop Iran 'very simply' from nuclear weapons as reporters ask questions in the Oval Office. Trump's answer was cut short as a young guest fainted, according to pool reporters in the room, ending the question-and-answer session. Reporters were in the Oval Office to see TV's Dr. Oz being sworn in as head of the agency responsible for Medicare and Medicaid. Pool reporters, photographers and cameramen were quickly pushed to exit the Oval Office. The White House later said that the young girl was okay.
