The play occurred in the 3rd period after the Caps scored to cut the lead to 1 with just over 6 minutes left in the contest. Hathaway was not happy, delivering a few stiff shoves to Subban after the fact.
Subban has done this several times this season, but with no real recourse, as the NHL's Department of Player Safety has, by all appearances, given Subban a pass on these types of plays, despite suspending others for the same offense.
