Despite its sanctuary policies, California’s undocumented immigrant population faces more questions and possible detention by federal authorities under new legislation signed into law Wednesday by President Donald Trump. “The law will have an impact on California,” said Kevin Johnson, dean of the UC Davis School of Law.

The Laken Riley Act, named for the slain nursing school student who was attacked and killed by a Venezuelan citizen who had entered the U.S. illegally, is the first legislative win of Trump's second term.

The legislation, known as the Laken Riley Act, is the first to be signed by the president in his new term, and shows how the politics of immigration have shifted.
