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.

The Minneapolis DFL’s endorsement of state Sen. Omar Fateh for mayor — the first mayoral endorsement by the local party in 16 years — is teeing up a competitive race between Democrats’ moderate and progressive wings.

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