The campaign for Mayor Jacob Frey is challenging the Minneapolis DFL endorsement of his rival, Minnesota Sen. Omar Fateh. According to a news release from Frey's campaign, the challenge was filed with the Minnesota DFL on Monday.

Minnesota Sen. Omar Fateh was in the hot seat, sitting through a Senate ethics investigation into an alleged quid pro quo with a Somali news outlet. On Saturday, Fateh was riding high, as Minneapolis Democrats endorsed him to be the city’s next mayor over incumbent two-term Mayor Jacob Frey.

The Minneapolis DFL held its convention on Saturday at Target Center, and Jacob Frey did not get the endorsement for mayor.
