Last week, U.S. Sen. Marco Rubio, R-Fla., brought out a proposal that imposes “immediate and harsh, personal sanctions on Vladimir Putin and the rest of the authoritarian leadership of Russia if Russian troops further invade Ukraine” and “would, for the first time, impose sanctions on Putin himself, and on the sectors of the Russian economy his regime depends on to personally enrich itself.’

Rubio, who sits on the U.S. Senate Foreign Relations Committee, introduced the “Deterring Authoritarian Hostilities Act” and weighed in on it.

“A core part of any strategy to force Vladimir Putin to back down is to make the consequences of an invasion extremely painful for the oligarchs that prop up his control of Russia,” Rubio said. “President Biden does not seem to understand that America must project strength and resolve, not weakness. I urge my Senate colleagues to work with me to pass this bill before it is too late.”

According to Rubio’s office, the bill would “block property belonging to and revoke visas of Vladimir Putin, the Russian Prime Minister, the Russian Defense Minister and other Russia oligarchs identified in reporting required by the Countering America’s Adversaries through Sanctions Act of 2017“ and “prohibit transactions with Russian companies in the Energy, Financial, Mining, and Aerospace sectors of the Russian Economy.”

Rubio’s bill was sent to the Foreign Relations Committee last week. So far, there are no co-sponsors and no companion measure over in the U.S. House.
