Former President Donald Trump on Saturday quoted Russian President Vladimir Putin to attack President Joe Biden as a “threat to democracy” and doubled down on language condemned for its ties to White supremacist rhetoric, saying at a campaign event in New Hampshire that immigrants are “poisoning the blood of our country.”

“Joe Biden is a threat to democracy. He’s a threat,” he told supporters at a rally in Durham, New Hampshire. “Even Vladimir Putin … says that Biden’s — and this is a quote – ‘politically motivated persecution of his political rival is very good for Russia because it shows the rottenness of the American political system, which cannot pretend to teach others about democracy.’”

Trump also praised two other authoritarian foreign leaders, calling Hungarian Prime Minister Viktor Orban “highly respected” and North Korean leader Kim Jong Un “very nice.”
