At a campaign rally in Nevada, President Donald Trump claimed Californians are "rioting" against "sanctuary cities" — a statement yet to be supported by evidence.

After deriding Rep. Jacky Rosen (D-Nev.) on her immigration policies at a rally in Elko, Trump told the crowd he thought Nevadians didn't care for sanctuary cities, and that Californians didn't like them either. Trump spoke in support of Sen. Dean Heller, Rosen's Republican opponent in the upcoming midterm election.

"They're rioting now," Trump said of Californians. "They want to get out of their sanctuary cities."

It's true that sanctuary cities have been a reliable topic of conversation and, particularly in the context of high-profile crimes such as the murders of Kate Steinle and Mollie Tibbets — homicide cases involving undocumented immigrants that received national attention— a source of contention.

But there has yet to be any evidence of rioting, especially in California. It's unclear what specific instances, if any, Trump's declaration was referring to.
