Top intel officials warn the Senate that Russian hacking is a threat to American democracyby Circa News

Two of America's top intelligence officials offered a fierce rebuke of President-elect Donald Trump's assertions there is no solid proof Russia was behind cyber attacks aimed at affecting the outcome of the 2016 presidential election.

Director of National Intelligence James Clapper and National Security Agency chief Michael Rogers testified before the Senate Armed Services Committee that they have credible evidence the Kremlin is the source of the hacks.

Senate Armed Services Chair John McCain, pictured here speaking with Sen. Elizabeth Warren (D-Mass.) ahead of Thursday's hearing, suggested Russia's hacking program is "an unprecedented attack on our democracy."

Trump has voiced support for WikiLeaks founder Julian Assange.

Clapper told McCain Assange has "no credibility."

Assange recently told the "Hannity" show that Russia was not the source of his leaks.
