Departing his home in Manhattan on Monday, Cohen teased that "there still remains much to be told".
Cohen then got into a black vehicle and drove off.
That December, Trump railed against his former attorney on Twitter, calling him a "rat", and by early the following year, Cohen took his campaign against Trump to Capitol Hill.
"For Mr. Cohen to claim he had major decision-making authority at the Trump Organization is ridiculous", Sorial writes.
Since mid-March, federal prosecutors in NY have rebuffed Cohen's repeated offers to provide more information about alleged wrongdoing by Trump and other people in his orbit, Davis said.
He is due to be held in the detention center's low-security "camp", which holds detainees who are not considered to be unsafe, including many other white-collar criminals.
On the day former Trump lawyer Michael Cohen is set to begin a "cushy" three-year prison sentence, Todd Piro looks back on the timeline of events that got him there.

Buffett also maintained that "we paid too much" for Kraft Heinz, which was created in a 2015 merger between Kraft Foods and H.J. Buffett told CNBC on Thursday that a money manager at Berkshire Hathaway has been buying shares in Amazon lately.
Michael Cohen reported to prison on Monday, almost five months after his sentencing.
In February congressional testimony, Cohen said, "I am ashamed that I chose to take part in concealing Mr. Trump's illicit acts rather than listening to my own conscience".
Mr. Cohen declined to pursue a formal cooperation agreement with the Manhattan federal prosecutors, which would have required him to disclose any crimes he may have committed or been aware of.
Father of two children in their 20s, Cohen had hoped until the last moment that his sentence would be reduced based on his readiness to cooperate with Special Counsel Robert Mueller's investigation into Russian election meddling, and, separately, NY prosecutors. They have two adult children, Samantha and Jake.
"Well, you never know how it's going to turn out", McaVoy said, noting that "It's still a jail, it's a prison, there are bad people there".
"Every Jew in the system wants to be there", said Levine, who prepares white-collar inmates to serve their time as founder of Wall Street Prison Consultants [Cohen is Jewish].
Cohen also said that Trump was aware of the scheme to pay Daniels 130,000 dollars in exchange for her silence about the alleged affair and that cheques to reimburse him were written during his time in office.
Cohen - who once famously claimed he was willing to "take a bullet" for Trump before later turning against his boss, including during nationally televised congressional testimony in February - pleaded guilty previous year to campaign finance violations, tax evasion and lying to Congress about Trump's past business dealings in Russian Federation.
