A pro-Russian blogger and YouTuber who also happened to be a U.S. citizen died in a Ukrainian prison last week.

According to the Daily Caller, and a report by former Fox News host Tucker Carlson, Gonzalo Lira suddenly died in Ukrainian captivity, with no cause of death revealed at this time.

Carlson opined on the situation during a recent episode of his exclusive X short-form news show.

"Gonzalo Lira, Sr. says his son has died at 55 in a Ukrainian prison, where he was being held for the crime of criticizing the Zelensky and Biden governments. Gonzalo Lira was an American citizen, but the Biden administration clearly supported his imprisonment and torture. Several weeks ago we spoke to his father, who predicted his son would be killed," Carlson wrote.

Ep. 47 Gonzalo Lira is an American citizen who’s been tortured in a Ukrainian prison since July, for the crime of criticizing Zelensky. Biden officials approve of this, because they’d like to apply the same standard here. The media agree. Here’s a statement from Gonzalo Lira’s… pic.twitter.com/4H2otHhYHi

In the original post, Carlson wrote, "Ep. 47 Gonzalo Lira is an American citizen who’s been tortured in a Ukrainian prison since July, for the crime of criticizing Zelensky."

He added, "Biden officials approve of this, because they’d like to apply the same standard here. The media agree. Here’s a statement from Gonzalo Lira’s father."

Lira was originally arrested for his anti-Ukrainian propaganda on May 1 las year by Ukraine's internal security agency, the SBU.

Newsweek noted:

Speaking about Lira's arrest, the Ukrainian government's Centre for Strategic Communication and Information Security, also known as SPRAVDI, said the YouTube poster had been charged with "justifying Russian aggression against Ukraine," in violation of Article 463-2 of the country's criminal code.

SPRAVDI spokespeople went on to point to specific remarks made by the U.S. citizen and YouTuber.

In July of 2023, Lira posted why he was arrested in an X post.

"On May 1, I was arrested for my YouTube videos. The photos of my arrest are pretty funny—morning bed-head made me look like a character out of Dr. Seuss. My crime was making videos critical of the West and their proxy regime in Kiev—and how they are destroying Ukraine," Lira wrote at the time.

In a follow-up post, he wrote, "As you can see, even the prosecutor admits I committed no crime against property or any person. And I certainly provided no aid or intelligence to the Russians."

Eerily, he later posted, "Right now, I’m about to try to get out of Ukraine, and seek political asylum in Hungary. Either I’ll cross the border and make it to safety, or I’ll be disappeared by the Kiev regime." Yikes.
