By Brad Brooks, Phil Stewart, Idrees Ali and Dietrich Knauth LOS ANGELES (Reuters) -Hundreds of U.S. Marines arrived in the Los Angeles area on Tuesday under orders from President Donald Trump, stirring street protesters and raising alarm among Democratic leaders who warn of authoritarianism.

U.S. President Donald Trump ordered the National Guard to be mobilized to quell protests in Los Angeles, despite California Gov. Gavin Newsom's objections. In a June 8 post on Truth Social, Trump claimed the troops had been successful even though the troops had not yet been deployed on the ground at the time of his post.
