Sen. Bernie Sanders had a rough night.

After getting shellacked by former Vice President Joe Biden in the South Carolina primary, the democratic socialist presidential candidate is said to have boarded the wrong private jet during a campaign stop on Saturday.

According to TMZ, Sanders suffered "a momentary case of a campaign brain fart" as he accidentally boarded the wrong private jet during a campaign stop between South Carolina and Massachusetts. He is said to have been spotted making his way off of a Gulfstream jet before heading to the "Bay State" for a rally in the Boston Common. The Democratic frontrunner is campaigning in fellow rival Sen. Elizabeth Warren's home state ahead of Super Tuesday, which polls show he is well-positioned to win.

Not the first time

This would not be the first time that Sanders is mocked for flying private.

As ABC News reporter Adam Kelsey tweeted in early February, both Sanders and Warren — who spend a considerable amount of time railing against jet-set billionaires on the campaign trail — were spotted using private jets following the Iowa Caucus.

'Not 1, not 2, but 3 Gulfstream jets'

Meanwhile, on Wednesday, a Twitter user claimed that Sanders and his campaign staff took not just one but three private jets to travel between Charleston and Myrtle Beach, South Carolina, which is only a two-hour drive according to Google Maps.

"[Sanders] and his entourage flew from Charleston to Myrtle Beach in not 1, not 2, but 3 Gulfstream jets today. It took them 10 minutes to fly. Who is the elitist?? #BernieIsACommunist," twitter user "CarolinaGirl" wrote.

TheBlaze has been unable to independently verify the veracity of these claims.
