Washington, Aug 7 : US Vice-President Kamala Harris has picked Tim Walz, the Democratic Governor of Minnesota, as her running mate, according to multiple media reports.

Walz, 60 is a former schoolteacher, a military veteran, a member of the House of Representatives, a two-term Governor and, in recent days, the man who coined the word "weird" to describe the Republican nominee for President, former President Donald Trump and his running mate, Senator J.D. Vance, and their campaign and their views that was quickly adopted by the Harris campaign and her allies.

The Harris campaign had not announced the pick till the filing of this report.

Walz is scheduled to make his first appearance along with Harris, who secured the official nomination of the Democratic party for President on Monday night, at an election rally in Philadelphia later on Tuesday and then go with her on a tour of battleground states.

"The window for delegates to vote in the virtual roll call has concluded, and that 99 per cent of the pledged and automatic delegates who fulfilled their responsibility by voting in the roll call cast their votes in support of Vice President Kamala Harris," the Democratic party said.

Harris had narrowed down her search to Walz and Josh Shapiro, the popular Governor of Philadelphia in the final days.

Shapiro was seen as a favourite with the expectation that he could bring some of his popularity in the battleground state to help Harris. He had won the Governor's race in 2022 with a 15 percentage point lead and Harris currently trails Trump by 2 percentage points. Additionally, Shapiro was seen as a moderate whose appeal extended beyond the Democratic party’s base. And he had many Republicans, who were not happy with Trump, rooting for him.
