Flynn, who pleaded guilty to the charge during a hearing in federal court in Washington, DC on Friday, rejected what he called "false accusations" that he is guilty of treason and other "outrageous acts", but said that he takes "full responsibility" for the actions he admitted to in court. Flynn also denied receiving a response to the request.
Flynn is the fourth former Trump associate to face charges in the investigation, the first who actually served in Trump's White House.
Jack Posobiec, an aggressively loyal social media Trump sycophant who was kicked out of a pizza restaurant for filming a child's birthday party in an attempt to discover the truth about "Pizzagate", made desperate attempts to spin for President Trump after news broke that General Mike Flynn had testified that officials from the Trump campaign instructed him to talk with Russians.
One of the officials, described as a "very senior member" of the presidential transition team, also directed Flynn to contact foreign government officials, including Russia's, about a UN Security Council resolution regarding Israeli settlements.
Flynn, who served in Donald Trump's administration for just 24 days before being forced to resign for misleading Vice President Mike Pence about his Russian Federation contacts, could be sentenced to up to five years in prison. "My guilty plea and agreement to cooperate with the Special Counsel's Office reflect a decision I made in the best interests of my family and of our country".
Flynn was forced to resign in February after intelligence leaks showed he had lied to Pence and other senior USA government officials about his conversations with Kislyak in late December, when Trump was still president-elect.
The Obama administration, in a rare step that shocked its Middle East ally, planned to abstain on the motion rather than veto it as had been done in the past.
Flynn's only comments were to answer yes and no to questions from the judge in the court.
White House lawyer Ty Cobb told The Associated Press that Flynn's guilty plea and pledge to cooperate with the Russian Federation investigation does not implicate "anyone other than Mr. Flynn".
"The false statements involved mirror the false statements to White House officials which resulted in his resignation in February of this year", Cobb said in a statement released to reporters. His business dealings and foreign interactions have made him a central focus of Mueller's investigation.
In January, the country's top intelligence chiefs said they had strong evidence showing Moscow had interfered in the campaign, by hacking and disinformation operations, specifically to boost Trump's chances of winning.
During the Republican National Convention in July 2016, when Trump was officially nominated as the GOP's candidate, Flynn led the entire convention in a repeated chant of "Lock her up!"
Warner noted that it's the second Trump campaign associate to plead guilty to making false statements, while former campaign chairman Paul Manafort and his deputy are facing a slew of charges.
Three others have been charged in the Mueller probe.
Apparently, Mueller's team was seeking a deal of some kind to win Flynn's cooperation in that investigation.
