Barack Obama can talk really tough when he's protecting his legacy or ordering around a bull.

President Joe Biden is stubbornly ignoring polls, pals, and former President Barack Obama, who are all allegedly telling the 81-year-old he needs to quit the 2024 race to save America and the Democratic Party, RadarOnline.com has learned.

Insiders snitched that tensions between the two presidents recently exploded after irate Obama rushed to a secret meeting and confronted Biden about his fading chances to fend off surging Republican candidate Donald Trump in the upcoming November election.

"Obama read Joe the riot act," spilled a Beltway insider to the National Enquirer. "He told him to up his game or step aside for a candidate who can win the race."

The Obamas are said to not support Biden in his run.

News of the shocking showdown came on the heels of damaging comments from former First Lady Michelle Obama, who politicos say is being pressured to mount a primary challenge to her hubby's aging former Veep.

Yes -- speaking of that, Megyn Kelly further gossiped about the possibility of Michelle Obama entering the race. The story goes that the scheme is already plotted -- Joe will announce his exit from the race in May, and then the delegates will choose Michelle Obama as the nominee at August's DNC.

Supposedly she already informed/polled the biggest Democrat donors and told them she's in.
