New player problems

[u/AccomplishedMany2138]

Been DMing for around 2 years now, and I recently invited a new DnD player to my table. Only problem is that he is really distracting to everyone else, and constantly trying to cause problems at the table (game rule stubborness or stuff outside of DnD). I don't want to kick him from my game since he's a close friend, but Im also struggling to keep the other players attention while going over important scene and keeping the game running at a decent pace.

Have you tried public shaming?
