Sam Bankman-Fried is paying the price for his interview with Tucker Carlson.

According to The New York Times, the disgraced crypto fraudster was placed in solitary confinement after prison authorities were alerted to the posting of a 45-minute interview with conservative talk show host Tucker Carlson.

A representative for the Bureau of Prisons told the Times that "this particular interview was not approved."

Prisons have strict rules about how inmates communicate with the outside world.
