Conor McGregor had a George Bush-like moment while at a media event in Moscow. If you can remember, Bush had a shoe thrown at him during a Middle East appearance back in December 2008, and McGregor had a similar situation occur while he was speaking. Just before the object was thrown the man can be heard saying, "Me and my brothers are cowards? Me, and my people and my father are cowards? What (did we) do to you?"
This appears to be a potential blowback from McGregor's recent comments about rival Khabib Nurmagomedov and his home country of Russia.
