|James O'Brien and Laurence Fox|
Fox retweeted O'Brien later that evening with a challenge.
When there was no immediate response from O'Brien, Fox followed up with a direct address.
Fox has previously offered to face some of his other detractors and met with Bonnie Greer pre-lockdown. Four days on O'Brien has not responded to Fox's challenge, which is somewhat odd for someone who sees himself as the intellectual almighty.
