Sen. Dianne Feinstein said Tuesday she “strongly supports” a federal law keeping the government from interfering in states like California that legalize marijuana use.

Long an opponent of legalized marijuana, Feinstein told the Sacramento Bee Tuesday that her stance on marijuana shifted through conversations with constituents, particularly those with young children who benefited from its medical use.

“Federal law enforcement agents should not arrest Californians who are adhering to California law,” Feinstein told the Bee.
