Republican State Representative Dave Williams, from Colorado Springs, went to the White House Thursday to pitch his plan to combat sanctuary cities.

Williams wants to hold elected officials, like Denver Mayor Michael Hancock, civilly liable when people in this country illegally commit crimes in cities where cooperation with immigration agents is limited.

Thursday he met with President Trump’s Domestic Policy Council to discuss the idea.

Williams has attacked the GOP frontrunner in the Colorado governor’s race, Walker Stapleton, for not supporting the idea. Stapleton's team did not respond to Next’s request for a comment Thursday afternoon.

Next surveyed the rest of the Republican candidates, as well. We not yet heard back from Attorney General and candidate Cynthia Coffman. Doug Robinson said he opposes the idea, while Victor Mitchell said he supports it.

According to the Colorado Springs Gazette, Williams wrote to Trump in August, asking him to crack down on sanctuary cities. Denver adopted an immigration ordinance late last year that prohibits using city resources to enforce federal immigration law.

State Reps. Steve Humphrey, from Severance, Tim Leonard, from Evergreen, and Kevin Van Winkle, from Highlands Ranch, accompanied Williams on the trip.
