Former President Barack Obama lied to the American people and tried to sabotage Trump's win, Senator Ted Cruz has claimed

US Senator Ted Cruz has compared the launch of the Trump-Russia investigation to the 1941 Japanese attack on Pearl Harbor, calling it a moment of "infamy" in American political history.

The Texas Republican made the remark on Fox News on Wednesday, accusing former President Barack Obama's administration of lying to the public and using federal agencies to undermine Donald Trump's presidency.

"December 9 should be a day that lives in infamy," Cruz said, referencing the date in 2016 when the FBI opened its inquiry and the famous wording Franklin D. Roosevelt used in a speech following a surprise Japanese attack on the US naval base in Hawaii. "That's a moment when senior members of our government decided to lie to the American people and sabotage President Donald Trump."

During a meeting on December 9, 2016, then President Obama ordered National Security Council officials to discard intelligence assessments that found no Russian involvement in Trump's campaign and replace them with claims blaming Moscow based on fabricated data, according to declassified documents released by US National Intelligence Director Tulsi Gabbard last week. Trump had defeated Democratic rival Hillary Clinton in the presidential election that November.

The scandal led to the years-long Trump-Russia probe known as 'Russiagate'. It severely damaged relations between Moscow and Washington, leading to sanctions, asset seizures, and a breakdown in normal diplomacy.

Russia has not yet commented on Gabbard's revelations. It has however consistently denied allegations that it interfered in the 2016 US election. The Kremlin has described the Russiagate affair as a politically motivated smear campaign intended to justify sanctions and worsen relations with Moscow.
