WASHINGTON — President Biden said Wednesday that he won’t change a thing about how he runs the country over the next two years in his first public comments since his fellow Democrats outperformed expectations in Tuesday’s midterm elections.

Biden spoke for 54 minutes at his third solo White House press conference and departed earlier than planned after a glaring gaffe in which he said Russia may pull back from the Iraqi city of Fallujah — when he intended to say the Ukrainian city of Kherson. 

Biden insisted in his opening remarks that “an overwhelming majority of the American people support elements of my economic agenda” and restated some of his most factually-challenged claims about his accomplishments — including taking credit once again for a decline in the federal deficit that is actually down to the end of temporary aid programs necessitated by the COVID-19 pandemic.

“Nothing,” Biden said when asked what he planned to do differently over the next two years ahead of a potential 2024 reelection bid, “because they’re just finding out what we’re doing. The more they know about what we’re doing, the more support there is.”

Later in the Q-and-A, the president said that he would likely make a final decision about seeking a second term early next year. Biden is already the oldest person ever to be president and would be 86 years old if he completes a second term in January 2029. 

The president later played pundit when asked about a potential Republican primary between former President Donald Trump and Florida Gov. Ron DeSantis, saying, “It will be fun watching them take on each other.”

Democrats dramatically outperformed polling in Tuesday’s midterm elections and control of the House and Senate remained up for grabs as vote-counting continued during the press conference. Although Biden shied away from swing states where he is less popular, the result is seen in Washington as boosting the likelihood that Biden will run again.

“This is ultimately a family decision. I think everybody wants me to run but we’re gonna have discussions about it,” Biden said, repeating his long-standing assertion that he intends to run but has not formally decided.

The president’s victory lap was derailed when he referred to the Ukrainian city of Kherson as “Fallujah” — and moments later struggled to say the word “apocalyptic” when discussing nuclear weapons.

Biden said at the outset that he had a list of 10 journalists to call on, but he departed after calling on just nine.

First lady Jill Biden sat in a special front-row seat carried into the State Dining Room just before the event, a notable occurrence after she reportedly tore into staffers in January for allowing Biden to take questions for nearly 2 hours at his most recent solo White House press conference. 

In his answers regarding the Russia-Ukraine conflict, Biden said it was “interesting” that Russia decided to pull out of Kherson only after the US election.

“It remains to be seen whether or not there’ll be a judgment made as to whether or not Ukraine is prepared to compromise with Russia,” Biden said, after his aides reportedly pressured Kyiv to show a willingness to talk with the Kremlin rather than try to drive Russian troops from all of Ukraine.

Asked in a follow-up question about his remark about Ukraine compromising, Biden said, “They’re gonna both lick their wounds and decide whether what they’re gonna do over the winter and decide whether or not they’re going to compromise… we’re not going to tell them what they have to do.”

At his most recent press conference in January, Biden enraged Ukrainian authorities by saying that NATO would treat a “minor incursion” by Russia differently from a full scale invasion. One Ukrainian official said that it gave a “green light” for Vladimir Putin to invade, which he did about a month later.

When asked about the possibility of a potential House Republican majority opening an investigation of first son Hunter Biden’s overseas business dealings, the president initially responded “lots of luck in your senior year, as my coach used to say,” before adding that he thought the American people wanted to “move on” from the revelations first reported by The Post more than two years ago. 

“It’s just an, almost comedy,” Biden said of investigations into his family’s international consulting businesses in places such as China and Ukraine. The president repeatedly met with his son’s business associates during his time as vice president and in the period before he ran for president and according to online records, Hunter Biden still co-owns a Chinese investment firm with state-owned entities.

Although he brushed off probes of his own family’s foreign links, Biden called for a federal investigation of Twitter owner Elon Musk‘s “cooperation and/or technical relationships with other countries” — saying when asked how, “There’s a lot of ways.”

Musk’s aerospace company SpaceX relies heavily on government contracts. His electric car company Tesla, meanwhile, will benefit from new tax breaks for buyers, but was snubbed last year by the White House when Biden refused to invite the non-unionized company to an electric car expo at the executive mansion, despite selling the most e-vehicles.

“While the press and the pundits were predicting a giant red wave, it didn’t happen,” said Biden, adding that “voters spoke clearly about their concerns.”

The president added that he was willing to work with Republicans in the wake of the inconclusive midterm results, but added that “the American people have made clear, I think, that they expect Republicans to be prepared to work with me as well.”

In the next breath, the president said that he would invite congressional leaders to the White House to exchange ideas after he returns from the G-20 summit in Indonesia later this month — before insisting in response to the first question asked of him that he had no intention of altering his big-spending agenda.

“I’m not going to change anything in any fundamental way,” Biden told a reporter for The Associated Press.

When pressed later by an NBC reporter, Biden added, “Well, let me put this way: what I meant was I don’t have to change any of the policies that have already passed. That’s what they said they want to go after… I have a simple proposition: I have a pen that can veto.”
