After visiting Russia earlier in the week, US Senator Ron Johnson expressed skepticism over the effectiveness of the US sanctions against Russia in an interview with the Washington Examiner.
"I think you'd be hard-pressed to say that sanctions against Russia are really working all that well," he said.
He noticed that while broad economic sanctions didn't not have "a real horrible effect," the personalized ones, aimed against Russian businessmen, "appeared to be" effective.

The US has imposed sanctions against 5 Russian organizations and 19 individuals over alleged meddling by the Kremlin in the 2016 US presidential elections — a claim that Robert Mueller's special investigative commission has failed to prove so far and which has been repeatedly denied by Moscow. The US president has labeled Muller's investigation and accusations by the Democrats of him having ties to Russia a "witch hunt."
Washington also imposed sanctions against 7 Russian businessmen in April of this year under the Countering America's Adversaries Through Sanctions Act (CAATSA).
