Before Tuesday, the U.S. had already imposed sanctions on Russia for its annexation of Crimea and aggressive military action in Ukraine. The latest round of sanctions expands the list of blacklisted businesses and individuals in Russia, targeting anyone “conducting malicious cyber activity on behalf of the Russian government.” The sanctions also pertain to those supplying weapons to the government of Syrian President Bashar al-Assad, who is backed by Russia. The U.S. has frequently accused the Assad regime of carrying out human rights abuses, the latest of which reportedly involved cremating the remains of thousands of hanged prisoners. Finally, the sanctions target Russia’s mining, metal, shipping, and railway sectors, parts of its energy sector, and individuals who have conducted business with its intelligence or defense sectors.

While the new sanctions package still awaits approval from the House of Representatives and a signature from the president, Tuesday’s sweeping bipartisan support suggests the deal is unlikely to be vetoed. In an effort to ensure the deal’s approval, senators also attached it as an amendment to a popular bill sanctioning Iran for its ballistic missile testing. Still, some Democrats are worried about how the White House will respond. One of the bill’s key negotiators, Ohio Senator Sherrod Brown, told reporters that “people in the White House, we hear, are making calls in the House to try to stop [the bill], slow it, weaken it, dilute it.”

On Tuesday, U.S. Secretary of State Rex Tillerson argued the Trump administration should have more oversight over future sanctions. While Tillerson admitted that “Russia must be held accountable for its meddling in U.S. elections,” he added: “We would ask for the flexibility to turn the heat up when we need to, but also to ensure that we have the ability to maintain a constructive dialogue.” The president, he said, should have the authority to “adjust sanctions to meet the needs of what is always an evolving diplomatic situation.”

But, for some of the deal’s most ardent supporters, diplomatic relations—or lack thereof—between the U.S. and Russia are less ambiguous. “Vladimir Putin’s brazen attack on our democracy is a flagrant demonstration of his disdain and disrespect for our nation,” said Arizona Senator John McCain shortly before the vote. “This should not just outrage every American, but it should compel us to action.” If Tuesday’s vote is any indication, most senators agree that firm action is necessary, but question whether Trump or his advisors feel the same.
