US television host Tucker Carlson announced on February 6 he would soon interview Russian President Vladimir Putin and urged Americans to watch the exchanges to learn what lay behind Moscow's 2022 invasion of Ukraine.Speaking from Moscow in a video published on his website, Carlson said the interview was to enable Americans to know "as much as you can" on Russia's view of the nearly two-year-old conflict with Ukraine.Later, the Kremlin said Putin granted an interview to Carlson on Tuesday because his approach differs from the one-sided reporting of many traditional Western.
