California attorney general: 'We're ready' to fight Trump administration over sanctuary cities

"We're in the business of public safety," not deportation, Xavier Becerra said.

Becerra contrasted the role of the federal government with California’s law enforcement agencies.

He said California abides by federal laws on immigration and asserted that the U.S. government cannot order state or local jurisdictions to change their approach to public safety.

"We're going to continue to abide by federal law and the U.S. Constitution,” Becerra said. “And we're hoping the federal government will also abide by the U.S. Constitution, which gives my state the right to decide how to do public safety.”

Stephanopoulos asked Becerra about Sessions' remarks in an earlier "This Week" interview Sunday. "You heard him. He's saying, especially in California, you're not fulfilling that duty" of cooperation, Stephanopoulos said.

"We can prove anywhere we need to ... that we are protecting our people," Becerra responded. "And we're doing it by keeping families together, not separating them."Stephanopoulos also asked the attorney general about the apparently confusing messages from the Trump administration on the status of DREAMers, unauthorized immigrants who were brought to the U.S. as children and who are currently protected from deportation by orders signed by former President Obama.

Trump on Friday said DREAMers should "rest easy," but Sessions said on "This Week" that they, like all unauthorized immigrants, are "subject to being deported."

"It's not clear what we can trust, what statement we can believe in" regarding DREAMers, Becerra said. "And that causes a great deal of not just anxiety, but confusion, not just for those immigrant families, but for our law enforcement personnel."
