U.S. Senate Republican leader Mitch McConnell added his voice on Monday to calls for bipartisan cooperation on investigations into Russian hacking aimed at interfering with the 2016 presidential election.

Axar.az informs, McConnell said: "Any foreign breach of our cybersecurity measures is disturbing and I strongly condemn any such efforts" at a news conference. "This simply cannot be a partisan issue."

Republican and Democratic senators have said they would cooperate in investigations into Moscow's role in the Nov. 8 vote. The calls for congressional action followed U.S. intelligence reports on Friday that Russia intervened in the presidential election on Republican President-elect Donald Trump's behalf through targeted hacking.

The Washington Post, citing sources briefed on the matter, said that when congressional leaders were briefed on the hacking report in September, McConnell had expressed doubts about the veracity of the intelligence.

But in comments on Monday that repudiated Trump's reluctance to blame Russia, McConnell said he had the highest confidence in the intelligence assessments of U.S. agencies, especially the CIA.

The lawmakers' rare display of bipartisanship to investigate hacking now contrasted with Trump's dismissal of the reports as "ridiculous" on Sunday, when he blamed Democrats for the news reports and said he did not believe they came from the Central Intelligence Agency.
