Regarding the contempt case, Bannon blatantly defied a lawful congressional subpoena — violations that a jury found him guilty of. This shouldn't surprise anyone, however, given Bannon's other legal troubles. The man who hindered a congressional investigation is also under indictment in New York on conspiracy charges after he fraudulently took donor money for what he falsely claimed would go toward building a border wall.
Bannon is in fact a political prisoner given that he's only sitting in jail due to his affiliation with Donald Trump. No one else in modern history has gone to jail for defying a congressional subpoena, but in the age of Trump, the establishment politicians and their friends in the weaponized Dept. of Justice have essentially persecuted their opponents. The Jan. 6 Committee was also improperly formed and run, which makes this entire saga fraudulent from the beginning.
