Prominent Democrat Pete Buttigieg has pledged to help US Vice President Kamala Harris win the election in November and described President Joe Biden as “among the best and most consequential presidents”.

The Transport Secretary on Sunday tweeted that Americans were much better off because of Biden’s leadership and accomplishments.

Buttigieg said on social media platform X that Harris was “the right person to take up the torch, defeat Donald Trump, and succeed Joe Biden as President”.

“I have seen her extraordinary leadership firsthand, working closely with her during the 2020 campaign and then in the historically effective Biden-Harris administration. I will do all that I can to help her win this election to lead America forward as our next President.”

Buttigieg recently described Republican presidential nominee Donald Trump’s vice presidential candidate J.D. Vance as someone who said whatever he needed to get ahead, and likened him to Mike Pence, who served as Trump’s vice president.

“I actually watched this exact same process with somebody else I got to know in my days in the Midwest, which is my former governor Mike Pence, who I watched start out as an evangelical Christian who cared about rectitude, family values, and then get on board with a guy [Trump] who was mixed up with a porn star, make excuses for him, so he could have power.

“And he did: he got four glorious years, I guess, as vice president of the United States,” Buttigieg told TV host Bill Maher.

“And it ended on the west front of the Capital with Trump supporters proposing that he be hanged for using the one shred of integrity he still had to stand up to an attempt to overthrow the government.

“So I guess maybe not as a politician but as a human being, what I’ll say is that I hope things work out better for J.D. Vance than it did for Mike Pence.”
