Russian Defense Minister Sergei Shoigu made his first public appearance Monday since a mercenary uprising demanded his ouster. He was shown inspecting troops in Ukraine in images aimed at projecting a sense of order after a weekend that saw armed rebels seize a Russian city and march seemingly unopposed on the capital. Shoigu is one of three powerful Russian leaders whose diverging interests led to the Wagner Group rebellion. He is the first to be seen since then. The mutiny marked the biggest challenge to President Vladimir Putin in more than 20 years of rule. Neither Wagner Group chief Yevgeny Prigozhin nor General Staff chief Gen. Valery Gerasimov has been seen or heard in public since the weekend.
