Not explicitly, but Nagornyi shared a post on his IG stories yesterday. The translation wasn’t super clear, but it was an organisation that seemed to be part of the Russian army and the post was about helping children in the independent Donetsk and Lugansk. Putin’s statement about recognizing those two as independent was pretty much the kick off for this war. So it didn’t look too good.
Edit: Khorkina had a post about praising the Russian army as well, though that seems to be much less surprising.
