This will be the first time that Vice President Harris and President Biden have appeared together on the campaign trail since Harris took over for Biden as the Democratic candidate's lead at a Labor Day event in Pennsylvania.
Harris' campaign said the vice president would spend Monday's holiday campaigning in Detroit and Pennsylvania. She will join Biden in Pittsburgh for an event to promote unions, her campaign said.
The two have previously appeared together at official White House events highlighting Medicare drug savings, but Monday will be their first time on the same campaign stage.
Pennsylvania is a key battleground in the November election, and Biden has previously indicated he plans to spend time in the state supporting Harris.
The joint event is part of the Harris campaign's planned Labor Day intensive.
In addition to Harris' two visits, the campaign said Minnesota Gov. Tim Walz (D) and his wife, Gwen, will spend the day in Milwaukee, and Lt. Gov. Doug Emhoff will attend an event in Newport News, Virginia.
The campaign said other election surrogates, including Illinois Gov. J.B. Pritzker (D) and campaign co-chair Mitch Landrieu, also plan to be deployed to battleground states.
Harris has many Major Labor Unions Harris has garnered support from union groups, including the United Auto Workers, since taking over from Biden as the Democratic candidate of the future. Biden has cast himself as the most pro-union president in history and picketed autoworkers during strikes last year, but Harris has signaled she intends to continue largely the same labor policies as Biden.
Former President Trump has repeatedly insisted that union members support his campaign, even as he clashed with union leaders, particularly Sean Fain, president of the National Federation of Labor, who has accused President Trump of being a “strikebreaker.”
Trump's allies argue that peeling away some of Biden's support from labor unions could make a difference in what is expected to be a close election: Trump lost union support by 14 percentage points against Biden in 2020.
