The US has a tradition of allowing former presidents to be briefed on the nation’s security issues – as a courtesy extended by the incumbent.
He cited Mr Trump’s “erratic behaviour” as his reason for refusing access.
“I don’t think there’s any need for him to have an intelligence briefing,” Mr Biden said in his first sit-down interview since becoming president.
He declined to speculate on what his worst fears would be if Mr Trump were allowed to see classified reports, but he suggested the former president could not be trusted to keep confidential information to himself.
“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?” Mr Biden said.
The move is the first time a former president has been excluded from the tradition of being granted continued access to the briefings, according to the New York Times.
Mr Trump feuded with the intelligence community throughout his four-year presidency and went through six national intelligence directors.
He questioned reports by US agencies that Russia had interfered in the 2016 election, and assailed intelligence chiefs for being “extremely passive and naive” over Iran.
In 2017, he disclosed highly classified information to Russia’s foreign minister about an Islamic State operation in what was seen as a breach of trust by many in the US intelligence community.
