The Democratic National Convention might take place too late for President Biden get on Ohio’s general election ballot, a top state official warned.

Secretary of State Frank LaRosa informed Ohio Democratic Party Chairwoman Liz Walters in a recent letter that the DNC convention is currently scheduled to convene on Aug. 19 but under state law presidential candidates must be certified by Aug. 7, creating all sorts of eligibility issues for Biden, NBC News reported.

LaRosa said the oversight can be remedied by either the Democratic Party moving up its nominating convention or by getting the Ohio state legislature to “create an exemption to this statutory requirement” by May 9 in accordance with state law.

A Biden campaign spokesperson said the campaign is “monitoring the situation in Ohio, and we’re confident that Joe Biden will be on the ballot in all 50 states.”

The Ohio Democratic Party told ABC News it’s reviewing the letter.
