twitter and facebook telling nbc news, they're actively removing accounts now and the pages of pro-russian networks. joining us, nbc news senior reporter, ben collins and katarina sadova is a research fellow and has family in ukraine. so ben, facebook, tiktok say they're also taking action. talk about the breadth of what's going on and what do we know about the impact that these trolls are having. >> sure, so, you know, russian propaganda has targeted ukraine for a long time. specifically in this case, with those fake faces that you just saw, the entire point is to make it look like ukraine is a failed state. and that they would be welcomed -- russia would be welcomed as liberators in ukraine. that's obviously not what's happening. as you can tell by the reality on the ground. russia is sort of losing the threat with its propaganda right now. both internally in russia. they're not getting the sort of widespread support that they thought they would get.
