In a sentencing memo filed by Flynn's defense team, President Donald Trump's former national security advisor claimed that law enforcement had failed to advise him that false statements he made could constitute a crime.
Prosecutors said Flynn had committed to a false story weeks before the January 24, 2017, interview with the FBI, having lied several times already to White House officials about his dialogue with ambassador Sergey Kislyak and then repeating those falsehoods to federal agents.
Regardless, it was Yates - accompanied by then-Acting Assistant Attorney General Mary McCord - who traveled to the White House two days later to inform the White House that Flynn had made false statements to the Federal Bureau of Investigation.
Strzok, who has repeatedly voiced his disdain for President Trump, was one of two agents sent by then-FBI Director James Comey to talk to Flynn at the White House in 2017.
On Feb. 21, 2018, Judge Sullivan filed what is known as a "Brady Ruling" instructing the prosecution team to hand over any exculpatory evidence to Flynn and his legal team that had been withheld from them up to that point.
Heck, a member of the House Intelligence Committee, said special counsel Robert Mueller's investigation into possible collusion between Russian operatives and Trump associates during the 2016 presidential campaign and transition is "getting closer and closer". Trump also plays a central role in a separate case in NY, where prosecutors have implicated him in a crime.
The mainstream media just spent the a year ago claiming Contreras' sudden removal from this case meant nothing much at all, and the subsequent 12 months of sentencing delays was due to all that awesome cooperation Flynn was supposedly giving to Mueller for his investigation into Trump and his associates.
Last year, however, Flynn departed the White House in a move Trump explained in a tweet at the time.
Amid Michael Cohen being sentenced to serve three years in prison, here's a look at where the investigations related to President Trump stand and what may lie ahead for him. Cohen implicated the President in August when he pleaded guilty in federal court and said that "in coordination and at the direction of a candidate for federal office", he had kept information that would have harmed Trump from becoming public during the campaign. "There was nothing to hide!"
Nevertheless, Flynn agreed to the interview, and told McCabe that he wouldn't bring with him any lawyers, which McCabe told Flynn would have required going through some extra hoops on his end at the Justice Department.
Former Trump national security adviser Michael Flynn leaves federal court in Washington, Dec. 1, 2017.
McCabe was sacked himself this year by then-Attorney General Jeff Sessions after Trump repeatedly complained about McCabe.
The back-and-forth between prosecutors and defense lawyers has created an unusual rupture in an otherwise harmonious relationship as prosecutors have praised Flynn as a model cooperator and have recommended no prison time at his sentencing.
Sessions, in turn, was sacked last month.
