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, as the city's mayor declared a curfew for parts of the downtown area and police arrested 197 people in a fifth day of street protests.

A cloud of uncertainty is hanging over Los Angeles, where questions remain over the role that Marines and National Guard troops will play after being called in by President Donald Trump amid protests over immigration raids in the city.

Demonstrators hit the streets again in L.A. after President Trump deployed the National Guard due to protests against ICE raids.

Calling President Trump a threat to the American way of life, Governor Gavin Newsom depicted the federal military intervention in Los Angeles as the onset of a much broader effort by Trump to overturn political and cultural norms at the heart of the nation’s democracy.

CLAIM: A Craigslist ad seeking “the toughest badasses in the city” is proof that Los Angeles demonstrations over immigration raids are made up of paid protesters.

Anti-ICE protests continue in Los Angeles after the National Guard was deployed following immigration enforcement actions.

Trump is begging for a fight on this. He knows what he’s doing so far is working with the American electorate," one data analyst noted

Another 2,000 National Guard troops along with 700 Marines are headed to Los Angeles on orders from President Donald Trump, escalating a military presence local officials and Gov. Gavin Newsom don’t want and the police chief says creates logistical challenges for safely handling protests.
