'What a foolish psycho': Trump's Father's Day rant slammed by critics — Biden among them

It's not an American holiday until former President Donald Trump issues his all-caps complaint and is immediately, and ruthlessly, mocked.

On Father's Day, Trump decided to celebrate his status as family patriarch with a lengthy tirade against "radical left degenerates" the former president, recently convicted on criminal charges, accused of "trying to influence" the judicial system against him.

President Joe Biden's campaign was quick to respond Sunday evening with a succinct synopsis.

"Convicted felon Trump posts a deranged, all caps 'Father’s Day' message attacking the judicial system and promising revenge and retribution against those who don’t support him," his campaign tweet reads.

Hours earlier, Trump — who has a history of marking holidays by posting angry rants against his foes — issued the following screed on Truth Social:

"HAPPY FATHER'S DAY TO ALL, INCLUDING THE RADICAL LEFT DEGENERATES THAT ARE RAPIDLY BRINGING THE UNITED STATES OF AMERICA INTO THIRD WORLD NATION STATUS WITH THEIR MANY ATTEMPTS AT TRYING TO INFLUENCE OUR SACRED COURT SYSTEM INTO BREAKING TO THEIR VERY SICK AND DANGEROUS WILL," he wrote.

"WE NEED STRENGTH AND LOYALTY TO OUR COUNTRY, AND ITS WONDERFUL CONSTITUTION. EVERYTHING WILL BE ON FULL DISPLAY COME NOVEMBER 5TH, 2024 - THE MOST IMPORTANT DAY IN THE HISTORY OF OUR COUNTRY. MAKE AMERICA GREAT AGAIN!!!"

The Biden-Harris campaign was not the only voice raising a sly eyebrow at Trump's comment, quickly flooded with dozens of messages of frustration, amusement and rage.

"He always has the worst holiday greetings of anyone I know," wrote X user Franklin.

"Such a narcissistic, small man," added Dawn Young-McDaniel.

"Yep, he is consistent in only one manner," replied Trish Davis, "Telling us what a foolish psycho he aspires to be."
