Under Putin, the Russian Government has decriminalised acts of domestic violence, enforced discriminatory LGBTQ laws, and been accused of repeatedly silencing writers and protestors who speak out against them. A list of some of the Russian government's most recent controversies can be found in the Human Rights Watch's World Report 2018.

Mashable has reached out to McGregor's representatives for comment.
