WASHINGTON (Reuters) - President Donald Trump, with two months left in office, asked for options on attacking Iran’s main nuclear site last week but ultimately decided against taking the dramatic step, a U.S. official said on Monday.Trump made the request during an Oval Office meeting on Thursday with his top national security aides, including Vice President Mike Pence, Secretary of State Mike Pompeo, new acting Defense Secretary Christopher Miller and General Mark Milley, chairman of the Joint Chiefs of Staff, the official said. Trump, who has refused to concede and is challenging the results of the Nov. 3 presidential election, is to hand over power to Democratic President-elect Joe Biden on Jan. 20. The official confirmed the account of the meeting in The New York Times, which reported that the advisers persuaded Trump not to go ahead with a strike because of the risk of a broader conflict. “He asked for options. They gave him the scenarios and he ultimately decided not to go forward,” the official said.
