Voters in Washington, D.C., who are planning to lend their support to Democratic presidential hopeful Bernie Sanders may have some trouble due to an error by the District of Columbia Democratic Party, according to a report from WRC.

As of Wednesday, Sanders' name had yet to appear to the ballot for the District's June 14 primary.

According to WRC, New Hampshire Sen. Sanders and former Secretary of State Hillary Clinton submitted registration fees to appear on the ballot earlier this month. The D.C. Democratic Party, however, failed to notify the District's Board of Elections about Sanders' registration until the day after the deadline passed on March 16.

It was not clear why the D.C. Democratic Party was delayed. Party officials told WRC the situation boiled down to a “minor administrative dispute,” but it may take a special D.C. Council vote to fix.

Twenty delegates will be at stake when the District's Democrats vote in the June 14 primary.

Republicans held their primary earlier this month, with Florida Sen. Marco Rubio taking 10 of the 19 delegates and Ohio Gov. John Kasich winning the remainder. Rubio has since dropped out of the race for the White House.
