Muslim leaders from several swing states on Saturday launched a national campaign against the reelection of President Joe Biden over his response to the Israel-Hamas war.

The launch took place in Dearborn, Michigan, and had Muslim leaders from states including Arizona, Minnesota, Wisconsin and Florida, Politico reports.

“We’re looking into finding ways to build a mechanism of coordination between all the swing states so that we’re constantly working together to ensure that Muslim Americans will come out in all of these states, and that Mr. Biden will lose each and every one of them,” said Hassan Abdel Salam, a professor at the University of Minnesota, during the launch.

Their main objection to Biden, according to the outlet, is that he has not sufficiently pressed Israel for a cease-fire in their war against Hamas.
