As the devastation in Ukraine increases, so do the calls to end the war. Among those championing tougher actions is Bill Browder—one of Putin’s most vocal critics—and the man behind the Magnitsky Act, which authorizes the U.S. government to sanction human rights offenders.

Browder has been advocating for expanding the list of sanctioned pro-Kremlin Russian oligarchs. He prescribes that Western lawyers, bankers, and other enablers of these oligarchs should also be held responsible.

Browder's new book, “Freezing Order: A True Story of Money Laundering, Murder, and Surviving Vladimir Putin's Wrath”, is out April 12.
