hi, bret. bret: this is america s newsroom. 36 hours of chaos threatening vladimir putin s grip on power. mercenary group that was supporting russia in ukraine turning against the kremlin and marching towards moscow. dana: the rebels were members of the wagner group. their leader called off the revolte at the 11th hour. not clear why. his whereabouts right now are unknown. ukrainian forces taking advantage of the chaos. they are reporting gains against russian troops in the east. russian defense minister is making his first public appearance since the revolt doing little to quell speculation that putin is in serious jeopardy. much of his longevity is tied to what happens inside ukraine. he knows full well his future is dependent on what happens in ukraine. i don t see him admitting that he made a terrible mistake here and pull all his troops out. you see a real public perception going against putin. he doesn t have a strong sense of being a strong man anymore. see
