Donald Trump suggested Thursday that presidents need immunity from prosecution even if they assassinate political rivals.

Trump addressed the media after appearing at his Manhattan civil court hearing and fielded questions. A reporter noted Trump's attorney had argued that a president couldn't be prosecuted if they used Seal Team 6 to assassinate a campaign opponent.

Trump did not disagree.

"I say this on immunity. Very simple. If a president of the United States does not have immunity, he'll be totally ineffective because he won't be able to do anything because it will mean he'll be prosecuted, strongly prosecuted, perhaps as soon as he leaves office by the opposing party," the former president replied.

Trump argued that Biden could be prosecuted for his immigration policies or the withdrawal from Afghanistan.

"You can get him on taking cash from countries," he said. "You could get him on the prosecutor not prosecuting his son or the company or whoever it was, Burisma in Ukraine, you could get him on that."

"If you don't have immunity, you can, you know, I mean, you won't be making any decisions, so you have to have it," Trump added.
