Schumer's comments came as the administration announced new sanctions against two-dozen Russian individuals and entities for cyberattacks in the U.S. and meddling in the 2016 election.

The U.S. released a joint statement with Germany, France and the United Kingdom on Thursday blaming Moscow for the poisoning of Sergei Skripal and his daughter, Yulia. The two remain hospitalized.
