Kamala Harris has picked Minnesota governor Tim Walz to be her running mate on Tuesday.
Harris and Walz will go up against Donald Trump and JD Vance this autumn in the race for the White House.
Harris will introduce Walz as her running mate and potential vice president at a rally on Tuesday evening in Philadelphia.
Walz, a 60-year-old U.S. Army National Guard veteran and former teacher, was elected to a Republican-leaning district in the House of Representatives in 2006 and served 12 years before being elected governor of Minnesota in 2018.
Harris’ campaign will hope Walz increases her chance of winning the mid-west state, which carries 10 electoral votes.
Harris chose Walz over Josh Shapiro, the governor of Pennsylvania, who had been seen as essential to delivering his battleground state.
The Harris campaign hopes Walz's extensive National Guard career, coupled with a successful run as a high school football coach, and his Dad joke videos, will attract such voters who are not yet dedicated to a second Trump term in the White House.
Harris, 59, has revived the Democratic Party's hopes of an election victory since becoming its candidate after President Joe Biden, 81, ended his failing reelection bid under party pressure on July 21.
