BUFFALO, N.Y. — ​Buffalo's mayor has not yet officially won his bid for re-election, though incumbent Byron Brown’s write-in campaign is still a source of some friction with the Democratic Party.

Multiple outlets, including Politico and the Wall Street Journal, report top progressive figures are calling for Brown to be removed from his position on the Democratic National Committee.

Members of the left-wing are reportedly upset that Brown decided to continue his campaign after losing the Democratic primary to India Walton. They claim he courted wealthy donors from both parties to help defeat a working-class candidate. Walton is echoing calls for Brown’s removal, claiming he renounced the Democratic Party in court and teamed up with Trump supporters to fuel his campaign.

Brown declared victory in the general election with 59% of votes cast for write-in candidates.

If that holds, it will be Brown’s fifth terms in office, making him the longest-serving mayor in Buffalo history.

Brown's campaign released a statement Thursday afternoon, saying:

"Mayor Brown is a life-long Democrat and has been a champion for the platform that makes the Democratic Party the party that stands for the values and goals of most Americans. As a Democratic Mayor and former State Party Chair he has fought for higher wages for fast food workers, a prevailing wage for people working on public works projects, the expansion of affordable housing, community policing and sensible criminal justice reforms, and making Buffalo a climate smart city. The Mayor will continue to uphold these values and support Democrats who embrace this widely popular approach to addressing the needs of everyday residents."
