Vladimir Putin scolded the US Senate Saturday for voting to tighten sanctions against Russia.

“It will, of course, complicate the Russian-American relationship,” the Russian president said in an interview. “I think it is harmful.”

The bill, which passed the Senate 98-2 on Thursday, is meant to punish Russia for its alleged interference in the 2016 election. It would require congressional approval of any changes to current sanctions and would allow for additional strictures on Russian shipping and mining companies.

The measure must still pass the House and be signed into law by President Trump.
