Tim Pool posted some pictures of a body contact incident with Acosta today on a Twitter thread. Acosta appeared on AC360 tonight. He has lost his press pass at the White House tonight. CNN has taken no action as far as I know so far.
More recent information (from Pool's tweets) suggests that Acosta was only reaching for a microphone when the body contact happened.
Update: Nov. 8
Tim Pool's take on this: Acosta has been a bit unprofessional.
