Senate Foreign Relations Committee ranking member Bob CorkerBob CorkerExxonMobil CEO, retired admiral will meet with Trump about State: report Conway: Trump expanding secretary of State field 'Apolitical' Petraeus says he did not vote in election MORE (R-Tenn.) called on President Obama to impose more sanctions on Russian companies to deter Russian military intervention in Ukraine.
Corker sent Obama a letter over the weekend, ahead of a European Union meeting on Russian sanctions Monday.
After Russia annexed Crimea, Congress passed a bill sanctioning Russian leaders involved in the military intervention and provided $1 billion in loans to Ukraine in an effort to protect its sovereignty.
Lawmakers have called for additional action as Russian President Vladimir Putin stations troops along the eastern border of Ukraine.
“Unless Russia ends its destabilization of eastern Ukraine and drastically reduces troop levels on the Ukrainian border immediately, further sanctions against strategic sectors of the Russian economy, particularly targeting Gazprom and additional important financial institutions, should be imposed within days,” Corker wrote. “A failure to respond to Russia’s recent actions will give the Kremlin a license to continue to threaten and undermine Ukraine, Moldova, and other countries in Europe and Eurasia.”
