Federal, state, and local authorities have dramatically increased security ahead of President-elect Donald Trump’s Monday inauguration but have still issued warnings to anyone who plans to be in Washington, D.C., to be on the lookout for potential “lone wolf” attacks,Trump’s swearing-in ceremony has been moved indoors, ostensibly due to a forecast of extremely cold temperatures in the nation’s capital, but authorities say there are still concerns over potential attacks, especially after Trump was targeted twice during his campaign, nearly losing his life when he was nicked by a sniper’s bullet in Butler, Pa., in July.
