Former President Bill Clinton’s fictional spy thriller has just sold hundreds of thousands of books. So he should have spent the weekend popping campaign and celebrating another pile of cash being added to his huge bank account.

Except this weekend, Bill’s Father’s Day was ruined by a 24 word message… from his alleged illegitimate son.

Danney Williams, a 32-year-old biracial man from Arkansas, claims he’s the offspring of an extramarital affair Bill Clinton had with his mother while she was working as a prostitute in Little Rock.

On Father’s Day, he called out Bill for allegedly abandoning him —

Even though you abandoned me and only took care of Chelsea, I still want to thank you for giving me life. Happy Father's Day @billclinton. pic.twitter.com/EMKla9lPM1

The charged Father’s Day message erupted on social media. There was an immediate outpouring of support for Williams, who has pushed this claim for years.

Williams backed calls for Bill to finally undergo a DNA test to prove — or disprove — his paternity claim.

One high powered donor called for President Donald Trump to use his presidential powers to compel Bill to take a DNA test this year.

Williams has asked for attention for his cause for two decades, but his claims have been largely ignored by the mainstream media. Williams claims have never been disproved, according to Snopes.com.

“Appearing at the National Press Club shortly before the 2016 election, Williams made an emotional plea to Clinton intern and lover Monica Lewinsky, but also to the people he says are his family,” according to The American Mirror.

“I also want to take this opportunity to appeal to my step-mom, Hillary Clinton. She has the power to have Bill Clinton provide a DNA sample,” Willaims said in the 2016 appearance. He had recently filed legal action to compel Bill to take a DNA test, but the case remains tied up in the court system to this day.

“I heard Hillary say she spent her life helping children. If black lives truly matter to her, why not mine? Why don’t you care about me, Hillary? Are you embarrassed about me? Hillary, are you ashamed of me? I am black, I am real,” Williams said. “Hillary, please don’t deny my existence. You are my step-mother, Chelsea is my sister, Bill Clinton is my father.”

Bill ignored the plea then. And on Sunday, he ignored Williams again.

Instead, the former president tweeted —

On this Father’s Day I’m thinking of the thousands of children separated from their parents at the border. These children should not be a negotiating tool. And reuniting them with their families would reaffirm America’s belief in & support for all parents who love their children.
