Pompeo vows to counter alleged Russian interference in U.S. polls

U.S. Secretary of State Mike Pompeo said here on Wednesday that the United States will not tolerate any Russia effort to interfere in the 2018 U.S. congressional mid-term elections, and will take action to counter Moscow.

While testifying before the House Foreign Affairs Committee on Capitol Hill, Pompeo said that the Trump administration will take "appropriate" countermeasures to fight Russia's continued efforts to meddle in November's vote.

However, he admitted that Washington has not yet set up "effective deterrence" to stop the alleged Russian meddling.

U.S. President Donald Trump has refuted Russia's interferences in the 2016 U.S. presidential elections, noting U.S. domestic calls for further investigation a "witch hunt" staged by the Democrats to cover their loss that year.

U.S. media said Trump believed such an investigation aims to delegitimize his presidency. Russia has repeatedly denied any involvement in the 2016 U.S. election.
