US Vice President Kamala Harris told supporters on Tuesday that she picked Minnesota's Governor Tim Walz as her deputy in the 2024 presidential election because he was a "battle-tested leader."

"Tim is a battle-tested leader who has an incredible track record of getting things done for Minnesota families," Harris said in a statement to supporters.

In the statement, which was extensively circulated on social and mainstream media, Harris stated that she trusted Walz to provide the "same principal leadership to our campaign, and to the office of the vice president."

President Joe Biden praised Harris' decision, calling it "an excellent one" and urging all Democrats to support Harris and Walz, calling the latter a strong, moral, and successful leader.

If Democrat Harris wins the November 5 presidential election, she will be the first American woman president and the second of color. Former President Donald Trump and Senator JD Vance are the Republican party's presidential and vice-presidential candidates.

Trump trailing Harris in presidential candidate support by 1%

Up to 50% of US voters want to vote for US Vice President Kamala Harris in the forthcoming presidential election, while 49% back Republican presidential candidate Donald Trump, a CBS News/YouGov survey released on Sunday revealed.

According to the findings, if a third contender emerged, 49% of respondents would favor Harris, 47% would choose Trump, and only 2% would prefer independent candidate Robert F. Kennedy Jr.

Harris secured Friday the Democratic presidential nomination, solidifying her position as the party's candidate for the November election against Republican Donald Trump.

Harris, the sole candidate on the ballot in a five-day electronic vote involving nearly 4,000 party delegates, will be officially nominated at a convention in Chicago later this month.

"I am honored to be the Democratic nominee for President of the United States," Harris said upon reaching the threshold.

Following President Joe Biden’s withdrawal from the race two weeks ago, Harris has become the uncontested leader of the party, marking a historic moment as the first Black and South Asian woman to secure a major party's nomination.

The Democratic Party opted for a virtual nomination process due to logistical challenges.

Harris' campaign expressed on Saturday disagreement with former President Donald Trump's choice to host a debate on Fox News on September 4. They urged him to adhere to prior commitments for debates scheduled on September 10.

"He needs to stop playing games and show up to the debate he already committed to on Sept 10. The Vice President will be there one way or the other to take the opportunity to speak to a prime time national audience," the campaign said on X.

The campaign suggested that Trump's announcement of debates on September 4 is an indication of his fear.
