Kamala Harris, the de facto Democratic nominee for US president, has named Tim Walz, the governor of Minnesota, as her running mate ahead of the November election.

The decision ends intense speculation over which candidate Harris would pick to go up against Donald Trump, the Republican nominee and former president, and his choice for vice-president, Ohio senator JD Vance, the Guardian reported. 

Walz first ran for office in 2006 in a Republican-leaning congressional district, upsetting the incumbent. He kept the seat until he won the Minnesota governorship in 2018, then again in 2022.
