WASHINGTON (AP) — Republicans are increasingly concerned that immigration enforcement is becoming a political liability in the upcoming midterm elections after two people were killed by federal agents during President Donald Trump’s crackdown in Minneapolis. A looming end-of-week funding deadline has brought the issue to a head in Congress, with Democrats vowing to block Homeland Security funding without significant changes and Republicans struggling to find their footing. Republicans have also struggled in elections without Trump on the ballot, a pattern that continued last year in New Jersey and Virginia. Republicans remain overwhelmingly supportive of his work on immigration, according to a Associated Press-NORC Center for Public Affairs Research survey conducted in January. A growing number of Senate Republicans have said they would be open to Democrats’ demand to separate Homeland Security funding from the broader package for further debate, while advancing the remaining bills.
