Roker asked him: “Are you saying that you would be taking part in our upcoming election in 2024? Help a brother out… make some news for me.”
The president said: “I plan on running, Al.”
He then added: “But we’re not prepared to announce it yet.”
The president has previously said it is his “intention” to run and it has been widely expected that he would seek re-election.
However, the timing of a formal announcement appeared to have been pushed back.
There had been an expectation Biden would announce his campaign in February, when he delivered the annual State of the Union Address.
Recent indications from the White House have suggested he may now wait until the northern summer to declare.
A White House spokesman said: “President Biden has been clear that he intends to run, and his focus is on finishing the work he’s doing for American families.
“There has never been a timeframe for any announcement.”
A source told NBC News: “The decision part is over”.
Some Democrat strategists are believed to want to delay the announcement so that Republican candidates can publicly attack each other before Biden enters the fray.
However, Biden will not be able to start raising money for his campaign until he declares his candidacy, so will need to join the race sooner rather than later.
It emerged on Monday that Biden intends to recruit hundreds of social media “influencers” to spread information about his first term political record.
The move is aimed at capitalising on his 26-point lead over Donald Trump in the 2020 election among voters aged 18 to 30.
Trump took time on Easter Sunday to ratchet up his attacks on Florida Governor Ron DeSantis, his main rival for the Republican presidential nomination in 2024.
The 76-year-old appeared to suggest that DeSantis, 44, should wait until 2028 to run.
He said: “Ron DeSantis is a young man who is not doing well against me in the polls, to put it mildly.
“I believe that if he decides to run for president, which will only hurt and somewhat divide the Republican Party, he will lose the cherished and massive MAGA vote, and never be able to successfully run for office again.”
Trump added: “If he remains governor, which is what Florida voters assumed, it would be a whole different story…. just sayin’ – But who knows?”
