If you mean Dmitry Rogozin, then yeah, he was a total dick (a part of which he has allegedly lost recently in Ukraine) who peddled all sorts of lies and oversaw the decline of Russian space capabilities.

I wouldn't be surprised if he expressed doubt over the Moon landings considering that he was also the one to push the absurd claim that the hole that had been drilled into a Soyuz was sabotage done by a space-crazed American female astronaut.
