Prigozhin denies plotting coup despite reports of unrest in Wagner army threatening Putin

Former Russian commander Igor Girkin claims the Wagner mercenary army and its leader Yevgeny Prigozhin pose an active threat to Putin's control.
The Wagner army is Putin's private military force made up largely of mercenaries fighting in Ukraine.
Prigozhin recently critized Russia's military leadership and suggested replacing top government officials.
Girkin worries Russia is heading towards defeat in Ukraine and the invasion is damaging Russia.
Prigozhin insists Wagner simply wants reforms in Russia and is too small to overthrow Putin, though US officials estimate it has up to 50,000 soldiers in Ukraine with major casualties.
