The Growing Tension Between Putin and Wagner's Prigozhin.

Yevgeny Prigozhin, the head of the Wagner mercenary group, has been publicly ranting at military leaders and even taking veiled shots at Russian President Vladimir Putin. Putin plays his factions off one another, which can fuel their anger. The Russian leader can't afford to target Prigozhin, but the Kremlin has other ways to keep him in check, according to a war expert. Prigozhin's endless fury is risking undermining his political benefactor, Putin, and laying bare rifts and apparent problems in the war effort.
