great to talk to you on this. first, i want to get your reaction from this news coming from facebook. >> for me, i think it's no reaction because we're doing this all the time. we spot them doing this kind of thing. for the public, it's good for them to be these are out there. what we have seen the russians do, particularly over the last year, is create lots of accounts and persona's appearing to be real authors, all using the deep fake photos, linked back to the same sell gram channels, internet websites. when you look, it looks like a genuine article. but there are just a handful of writers working for the russian government. i think it's great facebook and twitter have been able to take this down. it shows you they will go to any length to get their message out and try to undermine the ukrainians. >> we know how disinformation has played out in the age of this happening, especially with moscow behind it considering
