Former President Donald Trump is facing a myriad of legal problems, with Harvard Law School professor Alan Dershowitz recently predicted that he will be indicted by federal prosecutors on obstruction charges.

Yet this week, the Supreme Court agreed to hear a case involving Trump that is literally based on a joke. 

Attorney attempted to trademark "Trump too small"

According to Politico, California-based attorney Steve Elster has been selling t-shirts that bear the phrase "Trump too small" since 2018.

However, Elster's application to have his the phrase trademarked has been turned down on the grounds that federal law prohibits trademarks containing someone's name unless the person in question gives his or her written consent.

While a federal appellate court sided with Elster last year, the Biden administration has asked the Supreme Court to uphold the trademark rule.

Elster's slogan references a spat that played out between Trump and Florida Republican Sen. Marco Rubio during the 2016 presidential campaign.

During one Republican primary debate, Trump continuously referred to Rubio as "Little Marco." Rubio responded by dubbing Trump "big Don."

Following the clash, Rubio was seen suggesting to supporters at a campaign event that Trump's hands are abnormally small.

"He was calling me 'Little Marco,' and I'll admit he's taller than me," Rubio said. "He's about 6'2, which is why I don't understand why his hands are the size of someone who is 5'2. Have you seen his hands?"

Six years ago @marcorubio had the courage to openly mock #Trump’s “hand size” on the campaign trail. But on today’s Face The Nation, he didn’t even have the spine to admit that Trump was wrong about #Pence’s ability to overturn the 2020 election.

"Look at those hands. Are they small hands?"

That in turn lead Trump to tout the size of his hands and hold them up for audience members to see when he and Rubio again appeared on the same debate stage.

"He hit my hands. Nobody has ever hit my hands," Trump said of Rubio before adding, "I've never heard of this one. Look at those hands. Are they small hands?"
