Bernie Sanders fans in D.C. went on high alert yesterday when NBC Washington reported that the Vermont senator may not appear on the ballot for the June 14 primary.

While the Sanders campaign submitted his fees on time, the D.C. Democratic Party submitted the paperwork—from both the Sanders and Hillary Clinton’s campaigns—to the D.C. Board of Elections after the official deadline.

“All of the information was submitted at the same time,” says Margarita A. Mikhaylova, spokesperson for D.C. BOE. However, in addition to the $2,500 fee, Clinton also collected 1,000 signatures—a process the Sanders campaign forewent (in D.C., you can pay the $2,500 to avoid collecting the signatures).

The filing to the D.C. Board of Elections from Robert Brannum, the sergeant-of-arms of the Ward 5 Democrats is only about Sanders’ eligibility for the ballot, though.

“It is my declaration Candidate ‘Bernie’ Sanders submission for ballot access was late and not timely filled with the District of Columbia Board of Elections,” says the filing. “It is impermissible to allow filing deadlines to be ambiguous or different for candidates … It would be politically revolutionary to permit a candidate flaunt District of Columbia election rules designed to protect the voters.”

D.C. Democratic Party Chair Anita Bonds told The Washington Post that the delay was not an issue, and that in the past four elections, the names were submitted the following day without snafus.

Mikhaylova says there will be a D.C. BOE hearing next Wednesday over the challenge.

Bonds told NBC that the D.C. Council, where she serves an an at-large member, could hold an emergency vote as well.

According to the Post, three different D.C. Council members “called the situation embarrassing and sloppy, but said they would be willing to make sure all candidates who had submitted their information in good faith before the deadline make the ballot.”

The Sanders campaign said in a statement that they’re confident Sanders will appear on the ballot.

Even if Sanders does make it on the ballot, he’s got an uphill battle for the 46 delegates D.C. offers—Clinton has ten times more District donor dollars than anyone else in the race, either Democrat or Republican. Overall, her campaign has banked more than $5 million dollars from D.C. residents, compared to just over $271,000 raised by Bernie’s camp.
