Both California and the Trump administration will have to argue their sides in a lawsuit over immigration enforcement.
The Trump administration filed their lawsuit over California's sanctuary state laws late Tuesday. Their complaint argues the Supremacy Clause, which states that federal laws reign supreme.
But California Attorney General Xavier Becerra mentioned the 10th Amendment in his defense of California's immigration laws Wednesday. That amendment basically means any power not specifically given to the federal government is reserved for states.
We caught up with University of California, Davis Law School Dean and immigration expert Kevin Johnson about the lawsuit.
He said there is not really any precedent for the courts in this case, also noting that the federal government and California will have to work it out eventually.
"Lawsuits aren't decided by soundbites and who makes the best exaggerations," Johnson said. "They're decided by law and judges and justices in the end."
