COLUMBUS, Ohio -- Hillary Clinton and Bernie Sanders will headline an Ohio Democratic Party dinner here, less than two days before Ohio voters weigh in on the Democratic nominee for president.

Sanders and Clinton are headlining the party's annual legacy dinner at 6:30 p.m. at the Columbus Convention Center. The two will deliver separate speeches before heading north to Ohio State University to participate in a CNN town hall meeting.

Also expected to speak are the party's other top Ohio officials: U.S. Sen. Sherrod Brown, U.S. Rep. Joyce Beatty, party chairman David Pepper, and former governor and senate candidate Ted Strickland.

Party officials estimate 3,500 people will attend the dinner, with tickets ranging from $25 for College Democrats members to $5,000 for a table and four VIP reception tickets.

The event will be live streamed by the Ohio Democratic Party.
