Special counsel David Weiss opposes Hunter Biden’s request to delay his sentencing in a case involving illegal gun possession after Biden’s attorneys filed a motion on Tuesday seeking to push the hearing back by several weeks.

Lawyers for President Joe Biden‘s son cited scheduling conflicts with his other legal case in California as the reason for the requested delay, according to an eight-page motion. The first son recently pleaded guilty to nine tax charges to avoid a Golden State trial that would have dredged up potentially embarrassing testimony from witnesses, including his ex-girlfriends, about his behavior at a time when he was addicted to crack cocaine.
