Bernie Sanders is making his second campaign swing through Pennsylvania in two-and-a-half months, campaigning for the Democratic Party's nominee for lieutenant governor, John Fetterman.
Sunday's event is in Pittsburgh at Carnegie Mellon University.
The Vermont senator is making a three-state swing that's also taking him to Minnesota on Friday and Wisconsin on Saturday. Sanders lost Pennsylvania's presidential primary in 2016 to the party's eventual nominee Hillary Clinton.
Fetterman, however, endorsed Sanders for president and, while Sanders didn't endorse Fetterman in that year's Democratic U.S. Senate primary, he did endorse Fetterman in in the five-way lieutenant governor's primary.
Fetterman is running on a ticket with Democratic Gov. Tom Wolf against Republican gubernatorial nominee Scott Wagner and the GOP's nominee for lieutenant governor, Jeff Bartos.
