Tim Walz and JD Vance's 2024 VP debate is tomorrow. Here's what to know.

Washington — Sen. JD Vance of Ohio and Minnesota Gov. Tim Walz — both relative newcomers to the national political spotlight — face off Tuesday in the only scheduled vice-presidential debate before the November election.

The debate is being held three weeks after former President Donald Trump and Vice President Kamala Harris had their only scheduled debate. 

Walz, who is Harris' running mate, has had a long career in politics but was largely unknown to voters outside of Minnesota before he joined the Democratic ticket.
