Watch live: Vance campaigns in battleground Pennsylvania
Sen. JD Vance (R-Ohio), former President Trump's running mate, is rallying voters in the critical swing state of Pennsylvania Saturday.
His visit comes less than a week after Trump held two campaign events in the Keystone State, as he and his campaign have made it clear that the state could make or break his chances of winning in November.
With under a month left until the election, The Hill/Decision Desk HQ's aggregate of polls shows Vice President Harris with a razor-thin lead over Trump in the state — 48.6 percent to 48 percent.
The campaign event in Johnstown, Pa., is expected to speak at 2:30 p.m. EDT.
