Former President Barack Obama seems "very eager" to help ex-Vice President Joe Biden defeat President Trump.

Obama insiders reportedly expect the former president to campaign for Biden during the remainder of 2020, though he previously did not have confidence in the former vice president's ability to win the election.

“He is very eager to do this,” a former senior Obama official told the New York Post. "I certainly expect President Obama to be very active.”

Sources continued to say that Trump's presidency has left Obama "heartbroken," listing the federal government's response to the coronavirus pandemic as a reason for a change in leadership. “The coronavirus disaster and the [federal] government’s inability to lead on it is searing in his brain … more than anything else Trump has done,” a second insider told the New York Post. “Obama is generally heartbroken by the Donald Trump presidency.”

Obama issued his long-anticipated endorsement of Biden for president on Tuesday, several days after the Democrat secured his place as the only remaining candidate for the party's nomination. “Choosing Joe to be my vice president was one of the best decisions I ever made, and he became a close friend. And I believe Joe has all the qualities we need in a president right now,” Obama said in a video.

Prior to the endorsement, Trump speculated that Obama may "know something" that prompted him to withhold an earlier endorsement. "I don't know why President Obama hasn't supported Joe Biden a long time ago. There's something he feels is wrong," Trump said during a press briefing at the White House more than a week ago, adding, "He knows something that you don't know, that I think I know. But you don't know."

Biden reportedly did not inspire confidence in the former president. “You don’t have to do this, Joe, you really don’t,” Obama told Biden prior to his campaign launch, according to the New York Times.

However, with Biden as the presumptive Democratic nominee for president, Obama summoned top Biden aides to his Washington, D.C., office to develop campaign strategy. Obama instructed them that, whether the former vice president were to win or lose the presidential race, they cannot allow Biden to “embarrass himself” or “damage his legacy."
