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.

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.

White House "border czar" Tom Homan said that protests in Los Angeles are complicating immigration raids, making them more "difficult" and more "dangerous."

From Seattle and Austin to Chicago and Washington, D.C., marchers have chanted slogans, carried signs against ICE and snarled traffic through downtown avenues and outside federal offices.

The White House and Republican leaders in Congress are calling for quick passage of the centerpiece of President Trump's legislative agenda.

HOW WE GOT HERE: The protests erupted after Immigration Customs Enforcement (ICE) officers on Friday carried out raids in three locations across L.A., where dozens of people were taken into custody. Newsom called the raids “chaotic federal sweeps” that aimed to fill an “arbitrary arrest quota.”

This year’s BET Awards are scheduled to go on Monday night even as protests against immigration raids continue in Los Angeles, California.
