President Biden agrees in principal to meet with Russia’s Vladimir Putin, but a US official tells CBS News there is intelligence Moscow has given the go-ahead for Ukraine invasion.

CBS News National Security Correspondent David Martin says US Intelligence officials have intelligence that Russian troops have received orders to proceed with the invasion of Ukraine. He also adds “commanders on the ground are making specific plans for how they would maneuver in their sector of the battlefield. This comes after President Joe Biden said Friday he’s “convinced” that Russian President Vladimir Putin has decided to launch a further invasion in Ukraine, including an assault on its capital, Kyiv, as tensions spiked along the militarized border with attacks that the West called “false-flag” operations meant to establish a pretext for invasion.
