Gov. Janet Mills’ first ad buy as she seeks to unseat Sen. Susan Collins features a repudiation of ICE as Democrats nationwide seize on backlash over the agency’s aggressive tactics.

The new TV spot, shared first with Blue Light News, pairs news clippings and videos of ICE agents aggressively detaining people with footage of Mills criticizing the deportation campaign during her State of the State address on Tuesday.

“Our federal government has deployed masked law enforcement onto the streets, including here in Maine, stoking fear in our communities and killing American citizens in Minnesota,” Mills says in the ad. “It’s ridiculous, outrageous and unconstitutional.”

The six-figure buy goes up statewide on Friday and is running across broadcast and digital for the next two weeks.

It comes as immigration enforcement has become a national political issue, with voter backlash against ICE raids leading Democrats to talk more about an issue that had once been favorable for Republicans.

An ICE surge in Maine, dubbed Operation Catch of the Day by Homeland Security officials, received widespread backlash from Democrats and local leaders, who highlighted cases of Maine residents being detained by the agency despite having legal work permits and no criminal histories. The fatal shooting of Alex Pretti in Minneapolis last weekend further inflamed anger in Maine, too.

Collins announced Thursday that ICE would be halting its surge in the Pine Tree State, but the fallout of the heightened enforcement continues to roil the state. Mills’ decision to seize on ICE for her first ad is a sign she believes the issue will have staying power.

Mills’ main primary opponent, oysterman and political newcomer Graham Platner, has also gone after Collins on ICE this week, holding protests outside her offices in Portland and Bangor on Thursday.

Platner ran TV ads skeptical of Mills when the governor first jumped into the Senate race last fall. His campaign recently went up with more biographical spots and has pledged to stay on air through the June primary.
