President Trump slammed the mayor of one of America’s biggest cities after he tweeted a video assuring illegal immigrants of their constitutional rights.

Trump is visiting Los Angeles as part of a three-day West Coast tour that includes plans to speak with the organizers of the 2028 Olympic Games. On Sunday, Los Angeles Mayor Eric Garcetti tweeted his support for illegal immigrants, reminding them that the LA Police Department “does not coordinate with ICE or participate in immigration enforcement.”
