A crazed Bernie Sanders fan wearing nothing but cutoff jean shorts hopped into the Hudson River and began flailing and screaming about how he was “chased into the water by the CIA” on Wednesday.

“We are on the boat coming over and about half way across the river I see a guy bobbing in the water screaming for help,” recalled Scott Aufenanger, a 34-year-old from Hoboken who spotted the man in the water at around 12:20 p.m.

“He had a Bernie t-shirt in his hand,” Aufenanger told The Post, adding that the man claimed his name was Adam G.

“After he came up the ladder he was babbling. We sat down with him and he said, ‘I want to meet Bernie. I was chased into the water by the CIA. I hacked Hillary Clinton’s emails and they found out about it. They are planning on blowing up the Williamsburg bridge tomorrow.'”

Aufenanger was on his way to a work-related lunch when him and another Hoboken resident named Anthony Oland, 49, caught sight of the Bernie lover as he was fighting to stay afloat in the Hudson.

“He was almost exhausted,” Aufenanger said. “He wasn’t on the water’s edge — he was in the middle of the river. He was screaming ‘Help, I’m going to drown, I’m going to drown. Help me! help me! I didn’t mean to hurt anybody. I’m really sorry, I didn’t mean to hurt anybody.'”

The captain also saw the man and directed the boat towards him.

‘I want to meet Bernie. I was chased into the water by the CIA. I hacked Hillary Clinton’s emails and they found out about it. They are planning on blowing up the Williamsburg bridge tomorrow.’ - 'Adam G.'

“He was a short guy, he didn’t have an ounce of fat on him and he was tatted from head to toe,” Oland said. “We kicked off our shoes and walked on the foredeck. We assumed we would have to jump in.”

Instead, a ferry worker managed to pull the man to safety.

“The deckhand ran to the front of the boat where the Jacob’s ladder is and helped the man up,” Aufenanger said. “The captain told the man over the speaker, ‘swim toward the ladder.'”

After getting him on board, Adam G. had just one thing on his mind.

“He said, ‘I’m really sorry I let Bernie down’,” Oland recalled. “He said he was sleep deprived. He was shaking.”

Witnesses told The Post that the man appeared to have jumped in at the Midtown Ferry Terminal located at West 39th Street and 12th Avenue.

“We kept our hands on him to make sure he didn’t pop back into the water,” Aufenanger said. “We didn’t know if he was armed. He was yelling about Bernie and flailing in the river. He couldn’t remember how long he had been in the water. I asked him about his temperature and he said he was okay and then laid out his Bernie T-shirt on the deck like he was trying to show it to somebody. I don’t know who he was laying it out for, [ but] I was happy the guy was alive and not just a body bobbing.”

While the EMS responders were seen working on the man after he came into the Midtown ferry terminal, it was unclear whether he was arrested or transported to a medical facility.
