Police declared all of downtown Los Angeles to be an unlawful assembly area and ordered protesters to go home on Sunday night after a third day of violence hit demonstrations against President Donald Trump's immigration policy.

Trump ordered the deployment after immigration authorities driving in L.A. were hit with rocks, stones, and concrete, causing damage to government vehicles.

The National Guard was deployed in Los Angeles Sunday morning as President Trump responded to days of protest against federal immigration raids. Now, questions are being raised about the legality of the president mobilizing the guard without a request from the state's governor.
