Trump calls union leader who endorsed Kamala Harris ‘a stupid person’

The United Auto Workers' decision to endorse Kamala Harris's presidential run has apparently gotten under the skin of Donald Trump, who has responded by insulting the union's leader as "a stupid person".

In a new interview with Fox News on Sunday, as reported by the Hill, the former president said of union chief Shawn Fain: "Look, the United Auto Workers I know very well - they vote for me. They have a stupid person leading them, but they vote for me. They're going to love Donald Trump more than ever before."

Trump's remarks allude to the harsh 100% tariff he has proposed on imported cars. Economists have warned that such a tariff would raise product costs for Americans, but Trump has insisted on it, saying it reflects how he would prioritize the auto industry if returned to White House in November's election.

"We're going to take in a fortune but we're going to tariff those jobs," Trump said.

"We're bringing back the automobile industry and we're going to do that with tariffs," Trump said.

Fain and the UAW - one of the US's largest and most diverse labor unions - nonetheless gave their coveted endorsement to the vice-president, saying in a statement that Harris had a "proven track record of delivering for the working class".

Trump's comments about Fain and the UAW come just days after Fain announced that the union - one of the country's largest and most diverse - is endorsing Harris for president.

"We can put a billionaire back in office who stands against everything our union stands for, or we can elect Kamala Harris who will stand shoulder-to-shoulder with us in our war on corporate greed," said the statement announcing the UAW's endorsement for November's White House election.

Trump and the UAW have frequently traded barbs, with Trump calling for Fain to be "fired immediately" during his speech at the Republican national convention in July.

In response, the UAW called Trump a "scab" - a derogatory term for someone who abandons or refuses to join a labor union - as well as a corporate businessman whose main interest is protecting the wealthy.

When the UAW endorsed Joe Biden before the president quit his re-election campaign in July, Trump took to his Truth Social platform to attack Fain, calling him a "dope" and urging autoworkers to defy the union's endorsement by voting for him instead.

On Sunday, Fain appeared on CBS News's Face the Nation and elaborated on his union's decision to endorse Harris.

"When you put Kamala Harris and Donald Trump side-by-side, there's a very telling difference in who stands with working-class people and who left working-class people behind," Fain said.

He continued: "Trump's been all talk for working-class people.

"One of the biggest issues facing this country is inflation. It's not policy-driven. It's driven by corporate greed and consumer price gouging and that's what Donald Trump stands for. The rich get richer and the working class gets left behind."
