He's said several things about it, and has trashed the Russiagate conspiracy. He emphasizes both that the US interferes constantly in other elections, and also points out that Israeli collusion and interference in the US is orders of magnitude worse than Russian influence:
I think you're misinterpreting him. He doesn't say that it's not a bad thing, or that it's a hoax. He simply says that the US does the same thing abroad and it's hypocritical to not care about that part of it.
No, I don't believe I'm misinterpreting him. He is clearly showing heavy disdain for the assertion that the Russians had any material effect on US elections. He is also pointing out that there is the much greater issue of Israeli collusion that everyone, including yourself, is ignoring when the Russia collusion narrative is a "joke" (his words). Everyone please watch the video for yourselves. It's short.
