The Kremlin said on Monday that US President Joe Biden's remark that Vladimir Putin "cannot remain in power" was a cause for alarm, a guarded response to the first public call from the United States for an end to Putin's 22-year rule.
"For God's sake, this man cannot remain in power," Biden said on Saturday at the end of a speech to a crowd in Warsaw. He cast Russia's invasion of Ukraine as a battle in a much broader conflict between democracy and autocracy.
