In 2007, Joe Biden illegally entered the US Capitol

In 2007, Joe Biden said he was arrested and immediately released for illegally entering the US Capitol's Senate Chamber when he was 21 years old.

In 2021, Jacob Chansley was sentenced to four years in prison after spending ten months in solitary confinement for illegally entering the US Capitol's Senate Chamber.

Would this be considered a two-tiered justice system that prosecutes individuals based on their politics?
