ATLANTA (AP) — Republican state lawmakers seeking to aid President Donald Trump’s crackdown on illegal immigration are threatening local officials who resist with lawsuits, fines and even potential jail time.

Lawmakers in more than 20 states this year have filed legislation targeting so-called sanctuary policies that limit cooperation with federal immigration authorities, according to an Associated Press analysis using the bill-tracking software Plural.

Some of those states already ban sanctuary policies but are now proposing to punish mayors, council members and other government officials who violate the prohibition.

The goal is to provide “teeth to those who are being aggrieved by local governments and local officials who are not abiding by Georgia immigration law,” said Republican state Sen. Blake Tillery, whose legislation would allow lawsuits against anyone who implements sanctuary policies. His bill recently passed the Senate and is now in the House.
