During an appearing on Hill.TV’s "Rising" Shipton discussed the tour of America he and his father, John Shipton, concluded. The duo made their way across the U.S. to promote Assange's case in hopes of rallying public support and putting pressure on the Biden administration.

"The people we met across the U.S.... they understand the importance of this case and what it means to press freedoms and the first Amendment," Shipton said.

Assange, 50, is currently held in a maximum security prison outside of London.

Assange released classified documents in 2010 containing information about the Afghan and Iraq wars.

The Wikileaks founder was later charged in 2019 with “unlawfully obtaining and disclosing classified documents," and the U.S. government has sought to extradite him from the U.K.

"He's in prison with the most dangerous, violent criminals in the U.K.," Shipton said. "He's an innocent man. He doesn't have a sentence. And that's just another abuse of process that's been leveraged against him."

Shipton added that the past 12 years of attacks on his reputation, freedom and human dignity have taken a toll on his brother. 

"He's basically been crushed from the inside out."
