At the beginning of the interview, Micklethwait said Kamala Harris refused to appear to discuss her 'economic vision.' Probably a smart move.

Some highlights:

Trump slammed Micklethwait to his face over tariffs - saying "It must be hard for you to spend 25 years talking about tariffs as being negative and then have somebody explain to you that you're wrong." To which the crowd erupted in applause.

"It's going to have a massive effect, positive effect," Trump said. "The higher the tariff, the more likely it is that the company will come into the United States, and build a factory in the United States so it doesn't have to pay the tariff."

Of note, Trump's economic plan includes a 60% levy on imports from China and 10% duties on the rest of the world. Trump also vowed to block the sale of US Steel Corp. to Nippon Steel Corp if the $14.1 billion transaction wasn't concluded by the time he reenters office.

Trump then roasted the federal reserve, saying "It's the greatest job in government. You show up to the office once a month and say, 'Hmm, let's flip a coin,' and everybody talks about you like you're a god."

"I think it sets a horrible tone," said Trump, adding "There are certain companies you have to have."

Trump landed more hits when the topic moved to inflation. When Micklethwait noted that the WSJ says Trump's economic plan will increase the national debt by more than 7 trillion, Trump replied:

"What does the Wall Street Journal know? They've been wrong about everything. And so have you, by the way..."

"You're trying to turn this into a debate," Micklethwait shot back - to which Trump said "It's not a debate, but you've been wrong all your life on this stuff."
