Hunter Biden was unsuccessful in a bid to attend his initial appearance in Wilmington on felony gun charges via video conference.
The date for the in-person appearance was changed from late September to Oct. 3.
Hunter Biden is expected to plead not guilty to the charges.
The charges were filed after a plea deal fell apart when a federal judge handling the case questioned the scope of the agreement, which involved income tax and gun charges. The gun charges stem from a law that bars those addicted to drugs from owning a firearm.
Federal prosecutors said the agreement did not bar the government from continuing an investigation into Biden’s activities.
House Republicans have been holding hearings on the Biden case, with some members claiming Hunter received a “sweetheart deal” from the Delaware U.S. Attorney’s office headed by David Weiss, a Trump appointee. They have also claimed that the Biden family profited from Hunter’s activities.
Also involved in the case is Delaware Republican Party Chair and Seaford lawyer Julianne Murray, who made a filing in federal court. Murray earlier made an unsuccessful bid for Delaware governor.
