U.S. Sen. Rand Paul, R-Ky., took to Twitter Tuesday and aired his grievances about politics in honor of Festivus; he also provided a big tease about whether he will run for president in 2016. In the spirit of the fake holiday made popular by “Seinfeld,” Paul complained that his Democratic colleague, Sen. Cory Booker of New Jersey, doesn’t retweet his tweets as often and that Sen. Mitch McConnell, Kentucky’s other senator, won’t let him borrow his “awesome sweater vest.”

During his lengthy Airing of Grievances, which is part of the tradition of Festivus along with the Festivus Dinner and Feats of Strength, Paul also strongly hinted at a run for the presidency. The Kentucky senator is one of the most talked about possible candidates in 2016, but he has already announced he will run for reelection to the Senate, the seat of which is also up for grabs in 2016.

Paul pointed to his reaching across the political aisle with Booker on legalizing medical marijuana and reforming the criminal justice system. But Paul said his colleague doesn’t give him enough shoutouts on Twitter.

Paul also poked fun at Senate Minority Leader Mitch McConnell, R-Ky., and his fashion choices.

Paul, who practiced ophthalmology before being elected to the Senate in 2010, tweeted that medical ethics should also apply to politics.

Paul vowed to return to social media later on Tuesday to air more grievances “about the media, the Fed and a few others.” But he said he will spare Sen. Marco Rubio, R-Fla., from his complaints after the two traded barbs over President Obama’s Cuba policy.
