WASHINGTON — Far-left streamer Hasan Piker has been visibly rattled by the federal investigation into whether his jaunt to Cuba back in March violated US sanctions.

“This is not great,” Piker bluntly told his audience about the probe Sunday. “I mean it’s bulls—, but still not great that they’re after your boy. They’re up my ass.”

“Yeah, free me. Free me,” the 34-year-old riffed in response to a comment that flashed on his feed. “I can’t believe I’m saying that. But I’m about to be seemingly made an example of.”

Over the weekend, Fox News reported that the feds subpoenaed Piker and CodePink co-founder Medea Benjamin over their trip to the Communist island 90 miles off the coast of Florida.

Left-wing Rep. Jasmine Crockett (D-Texas) added salt to Piker’s wounds by reposting a mocking video needling him for declining to vote for former Vice President Kamala Harris in 2024.

“I mean Kamala would have never,” Threads user TalkUrShxxtNene chided Piker in the video, to which Crockett reacted with sideye emojis. “That’s what you get for telling people to vote third party or not vote at all.”

Piker and Benjamin were two of more than three dozen individuals under investigation by the Treasury Department’s Office of Foreign Assets Control.

The subpoenas for communications and other relevant documents came in response to an online rumor that Piker and his comrades stayed at a US-sanctioned hotel in Havana. Participants in the trip have denied that rumor.

The Treasury Department declined to comment when asked by The Post about the investigation.

The Treasury’s Cuban Assets Control Regulations place tight restrictions on dealings with Cuba, particularly regarding certain hotels and other businesses that have direct ties to the government.

There are carveouts for humanitarian initiatives, as well as journalism, education, and similar ventures.

Piker was among hundreds of lefties who joined the “Nuestra America Convoy,” featuring socialists from Europe and North America, who traveled to Cuba under the pretense of distributing humanitarian aid.

That trip was a response to President Trump’s aggressive pressure campaign against Havana, which is undergoing an energy crisis following the January apprehension of Venezuelan President Nicolas Maduro.

“The Trump administration is investigating people for bringing medicine to Cuban children while defending policies that deprive those same children of food, fuel, and basic medical supplies,” Benjamin raged on X Sunday. “If loving the Cuban people is a crime, then millions around the world are guilty too.”

Piker, a nephew of “Young Turks” host Cenk Uygur, has a history of inflammatory and hateful rhetoric.

Infamously, he declared in 2019 that “America deserved 9/11″ and later claimed the Oct. 7, 2023, Hamas attack was a “direct consequence” of Israeli actions, adding that even if the terror group engaged in rape, it “doesn’t change the dynamic for me.”

Piker has also gushed over the “brave mujahideen” who injured Rep. Dan Crenshaw (R-Texas) during his military service in Afghanistan — and even suggested that Sen. Rick Scott (R-Fla.) should die.
