MADISON, Wis. (AP) — Democratic U.S. Rep. Mark Pocan on Friday asked U.S. Attorney General Merrick Garland for a Justice Department investigation into 10 Republican electors who submitted false paperwork last year saying former President Donald Trump had won in the battleground state.

President Joe Biden carried Wisconsin by just under 21,000 votes. The Republicans who met have defended the move, saying they were submitting the votes in case Trump’s loss was overturned by the courts.

Pocan said it was imperative for the Justice Department to act “to deter other officials who may seek to engage in election fraud.” He urged Garland to act quickly “for Wisconsin, for the Department, and for the nation.”
