Tonight' host criticized the president for sending National Guard troops and Marines into Los Angeles: "Why would you send troops if there is nothing for them to do?"

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

The Trump administration faces a legal challenge to its deployment of the military to protests. Tensions flared after President Trump sent troops, and protests spread to other U.S. cities.

Los Angeles is one of hundreds of places across the U.S. seeing massive protests against the Trump administration, although L.A. has already seen a week of demonstrations against the immigration policies of President Trump.

Police in Los Angeles, where protests over federal immigration enforcement raids erupted a week earlier and sparked demonstrations across the country, used tear gas and crowd-control munitions to clear out protesters on Saturday.
