Steve Cohen wins Democratic primary Democrats exit briefing saying they fear elections under foreign threat Texas Democrat proposes legislation requiring masks in federal facilities MORE (D-Tenn.) on Tuesday said that Russian hacking efforts against the U.S. amount to an act of war and the U.S. should have countered by launching cyber attacks against the Kremlin.

"No question about it," Cohen told Hill.TV's Buck Sexton and Krystal Ball on "Rising" when asked whether the Russian hacking and propaganda effort constituted an act of war.

"It was a foreign interference with our basic Democratic values. The underpinnings of Democratic society is elections, and free elections, and they invaded our country," he continued.

Cohen went on to say that the U.S. should have countered with a cyber attack on Russia.

"A cyber attack that made Russian society valueless. They could have gone into Russian banks, Russian government. Our cyber abilities are such that we could have attacked them with a cyber attack that would have crippled Russia," he said.

Cohen's comments come one day after President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'
