The event will take place at 6:30 p.m. in McLean, according to the White House.
Other details were not available and the Kaine campaign did not immediately return a request for information.
Kaine will likely face Republican George Allen, who is the front-runner in a four-way race for the GOP nomination.
Republicans, including Allen, have criticized Kaine, former chairman of the Democratic National Committee, for his ties to the Obama administration. Kaine has not shied away from Obama in his race, though he has broken with him on a handful of issues.
