Vladimir Kara-Murza: “I call on the U.S. Government to fight harder for the release of those who risked their lives.”

It is absolutely imperative that any agreement, any cease fire agreement includes a provision on the release of all the captives of this war.

The criminals are those who are waging this war, not those of us who are speaking out against.

There are absolutely no limits to what Vladimir Putin can do. I think the world is seeing this loud and clear now as we're witnessing this large scale land war, this large scale war crime happening right at the heart of Europe.

Putin does this because he keeps getting away with it. He got away within Syria. He definitely got away with it in Chechnya.
