"We have people coming into the country, or trying to come in, we're stopping a lot of them, but we're taking people out of the country, you wouldn't believe how bad these people are", Trump said during a meeting with California lawmakers and officials who oppose their state's policies on sanctuary cities.
SB 54, which has been in effect since January 1, limits state and local law enforcement cooperation with federal immigration authorities.
"The state of California's attempts to nullify federal law has sparked a rebellion by patriotic citizens who want their families protected and their border secured", Trump said at the start of the meeting. "They want border security and they want protection".
California state Rep. Melissa Melendez, who represents parts of Riverside County, echoed the president's comments.

"Mexico does nothing for us", he said.
"I think it is heartless".
During the session, Mr. Trump suggested that the mayor of Oakland, Calif., should be charged with obstruction of justice for warning her constituents in February of an impending large-scale immigration raid and arrests.

"The concept (of sanctuary laws) that we are even talking about is so ridiculous, " the president said.

"My Administration stands in solidarity with the fearless citizens in Orange County defending their rights against California's illegal and unconstitutional Sanctuary policies", he tweeted.
