The Federal Court of Justice rejected the request from Markus Braun, who has been detained since July pending a trial on charges of fraud and embezzlement, according a letter, seen by Reuters, sent by the court to the parliamentary committee that will hear him.

Braun, and several other accused, deny any wrongdoing.

His laywers had argued that the circumstances of the coronavirus pandemic made it unnecessarily risky for him to testify in person, especially when the necessity of providing prisoner transport was considered.
