Montana city under investigation for potential violation of sanctuary city ban

Montana's Republican attorney general said Wednesday he's investigating the city of Helena for potential violations of the state's sanctuary city ban, after city officials passed a resolution discouraging cooperation with federal immigration authorities. The investigation comes amid heightened tensions nationally over President Donald Trump's aggressive enforcement of immigration laws, which has sparked protests in many cities. Trump has said he intends to cut off federal funding for states home to “sanctuary cities” that resist his immigration policies.
