Sen. Ben Cardin (D-Md.) said on Sunday that the armed rebellion from the Wagner Group shows Russian President Vladimir Putin’s power is waning among his people. In an interview with Shannon Bream on “Fox News Sunday,” Cardin pointed to the rebellion by Yevgeny Prigozhin’s Wagner Group as evidence of Putin’s declining credibility, even among his longtime allies. “Putin has lost his credibility with his own people. His account of why he went into Ukraine is now being challenged, I think, with public opinion and Russia itself,” Cardin told Bream.
