US President Joe Biden told CBS News in an interview he does not think former President Donald Trump should continue to receive intelligence briefings.

The full interview with "CBS Evening News" anchor and managing editor Norah O'Donnell will air in full ahead of the Super Bowl on Sunday.

Former presidents often have the opportunity to receive intelligence briefings as a courtesy, but when asked by O’Donnell asked Biden if Trump should still receive intelligence briefings, he replied, "I think not.”

Biden explained his reasoning in Trump’s “erratic behavior unrelated to the insurrection”.

The president did not elaborate on his concerns about what might happen if Trump continues to receive the briefings, but questioned what value that could add for the country.

"I'd rather not speculate out loud," he said. "I just think that there is no need for him to have the intelligence briefings. What value is giving him an intelligence briefing? What impact does he have at all, other than the fact he might slip and say something?"

Biden declined to say whether he thought that Trump should be convicted in a Senate impeachment trial, which is scheduled to start on Tuesday.

“I ran like hell to defeat him because I thought he was unfit to be president. I’ve watched what everybody else watched, what happened when that– that crew invaded the United States Congress. But– I’m not in the Senate now. I’ll let the Senate make that decision,” he said.
