But Donilon, who was the top strategist for both Biden's 2020 and 2024 campaigns, would have apparently earned some $8 million total if Biden won.
Donilon told investigators that he was paid $4 million to work on Biden's 2024 campaign, the source said, information that was reported by Axios reporter Alex Thompson and CNN host Jake Tapper in their book "Original Sin: President Biden's Decline, Its Cover-up, and His Disastrous Choice to Run Again."
The $4 million he would have gained in addition would have come if Biden won.
Biden infamously dropped out of the 2024 race after his disastrous debate against now-President Donald Trump in June of that year, following weeks of mounting pressure by fellow Democrats – both in public and in private.

"I was with President Joe Biden from his first day in office to the last day. What I saw, day in and day out, was a leader who was deeply engaged and in command on critical issues, both at home and abroad. Every President ages over the four years of a presidency and President Biden did as well, but he also continued to grow stronger and wiser as a leader as a result of being tested by some of the most difficult challenges any President has ever faced," Donilon said his statement.
"I thought that experience was enormously valuable for the nation. I believed that President Biden was the best person to lead the country on the day he took the oath of office and I continued to believe that was true every day he served as President."
Donilon is the eighth ex-Biden White House official to appear for the probe, being led by House Oversight Committee Chairman James Comer, R-Ky.
Fox News Digital reached out to Donilon's lawyer and a representative for Biden for comment.
