Vice President Kamala Harris has returned to the campaign trail for the first time since accepting her party's presidential nomination at last week's Democratic National Convention. This comes as the Trump/Vance team asserts they are better prepared to manage the economy than Harris.

Harris boarded a bus in Savannah to kick off a tour of southern Georgia, a key battleground state that Biden won in 2020 by less than 12,000 votes. Harris and her running mate, Minnesota Governor Tim Walz, will spend Wednesday and Thursday campaigning in the state. New CBS News polling shows Harris and former President Donald Trump tied in Georgia.

Trump's running mate, JD Vance, is campaigning in another critical battleground—Pennsylvania—where the candidates are also in a tight race. The Trump campaign is focusing this week on the "Blue Wall" states of Pennsylvania, Wisconsin, and Michigan, all of which Biden narrowly won in the last election after Trump flipped them in 2016.

Vance emphasized the importance of border security to the U.S. economy during his campaign stop.

"We're going to stop 25 million illegal aliens coming into this country and competing for wages against American workers," Vance said.

Earlier Wednesday, Governor Walz worked to bolster labor support by speaking with firefighters at a union convention in Boston, where he shared a personal story about St. Paul Fire Captain Chris Parsons, who died in the line of duty.

"It's the kind of heartbreak that no family and no community should have to endure because every hero deserves to come home at the end of every shift," Walz said.

On Thursday, Walz and Harris have agreed to a sit-down interview with CNN—her first since declaring her bid for president. Harris is also set to campaign alongside President Biden in Pittsburgh on Labor Day, marking another first. Biden will campaign for Harris in Wisconsin next week.
