On July 27, U.S. Magistrate Judge Lauren Louis set a detention hearing for Aug. 13 to determine whether the Tates should be released during an extradition process that could last for months—or remain behind bars.

The brothers, who have been in custody since making a brief court appearance two days after their July 18 arrest, were not required to appear on Monday and were not present when the judge continued their detention.

Joseph McBride, an attorney for the brothers, has said they will fight extradition and that they maintain their innocence. He described the attempt to extradite the brothers as politically motivated.

McBride told reporters after their initial court appearance on July 20 that the brothers did not do anything wrong.

"They shouldn't be extradited for crimes they did not commit," he said.

McBride said Monday that he wants the U.S. government to provide the materials British authorities submitted to secure their arrests.

"They don't have anything but the accusations," McBride said after the hearing. "It's just their word against our word right now."

Assistant U.S. Attorney Alejandra Lopez said the UK has until mid-September to submit its supporting materials to the State Department.

'Why Am I Here?'

In remarks to the New York Post on Monday, McBride said he meets with Andrew Tate as many as six times a week and jots down the influencer's thoughts so they can later be posted on social media.

McBride described the arrangement, which allows Tate to continue reaching his millions of online followers from jail, as the "Pony Express."

"There's a way to be like, 'What would you like said to the world?'" McBride said. "It's not very hard."

In one July 27 post, Tate complained about being held in a special housing unit, an isolated section of the jail typically used either to protect inmates or punish misconduct.

"This is punitive housing for people who murder their cellmates," Tate wrote. "No commissary, no phone calls, no yard time."

Describing himself as an "innocent until proven guilty extradition detainee," Tate noted that he is a U.S. citizen wanted by a foreign government and questioned the reason for his detention.
