If legitimate, Flynn's cooperation with the prosecution would give the special counsel investigation insight into the Trump campaign's operations and the early days of Mr. Trump's presidency.
Michael Flynn's legal team recently informed President Trump's lawyers that they can no longer discuss special counsel Robert Mueller's investigation - a move that indicates Flynn, Mr. Trump's former national security adviser, may now be cooperating with the investigation into potential Russian interference in the 2016 US presidential election and Trump campaign collusion with the Kremlin.
"Mr. Flynn is regarded as loyal to Mr. Trump, but he has in recent weeks expressed serious concerns to friends that prosecutors will bring charges against his son, Michael Flynn Jr., who served as his father's chief of staff and was a part of several financial deals involving the elder Mr. Flynn that Mr. Mueller is scrutinizing", according to the Times.
The Times reportedly has four sources to confirm the split.
The legal manoeuvre, while not proving they have flipped and chose to co-operate with Mueller's investigators, "is the clearest indication we've seen to date that Flynn is co-operating with prosecutors", said former federal prosecutor Barak Cohen. Forget wasting our money playing golf.
His ties to Russian Federation predated the campaign - he sat with President Vladimir V. Putin at a 2015 event in Moscow - and he was a point person on the transition team for dealing with Russian Federation.More news: Vladimir Putin signs new Russian law for foreign media outlets
He resigned his position as national security adviser in February following revelations that he misled Vice President Mike Pence about his communications with Russia's ambassador to the U.S., Sergey Kislyak.
"No one should draw the conclusion that this means anything about General Flynn cooperating against the president", Sekulow told CNN.
Flynn initially told investigators that he did not discuss sanctions with Kislyak during a December call, but when later pressed by Federal Bureau of Investigation agents, he changed his answer, claiming he didn't remember.
Now it appears that Flynn might already be divulging what he knows, and likely opening a line of communication with special counsel Robert Mueller's investigators.
For his part, Abramson argues the Trump-Flynn legal information-swapping was ethically dubious from the get-go. That film would have revolved around exiled Turkish cleric, Fethullah Gulen, whom Ankara has accused of trying to overthrow Turkish President Recep Tayyip Edorgan past year, people familiar with the investigation told the Journal.
Turkish officials accuse Gulen of being a terrorist and trying to foment a failed coup attempt in Turkey. The report stated that it was the first clear indication that Flynn might be "negotiating a deal" with Mueller. If Flynn has made a decision to formally consider cooperating with prosecutors, then it would be standard practice for his lawyers to quit talking shop with Trump's team.
