Judge William Pauley walked through each of the counts against Cohen, saying "each of these crimes is a serious offense against the United States."
"Mr. Cohen pled guilty to a veritable smorgasbord of fraudulent conduct," he said.
Michael Cohen has finished speaking in his sentencing hearing.
In his statement to the judge, he took responsibility "for each act that I pled guilty to: The personal ones to me and those involving the President of the United States of America."
During his remarks to the courtroom Cohen, while referring to President Trump, said that he is committed to “ensuring that history will not remember me as the villain of his story.”
The federal judge is now speaking.
Michael Cohen just addressed a tweet from his former boss, President Donald Trump.
"Recently the President tweeted a statement calling me weak and it was correct but for a much different reason than he was implying. It was because time and time again I felt it was my duty to cover up his dirty deeds."
Cohen also called this "one of the most meaningful days of his life."
"This may seem hard to believe," Cohen told the court, "but today is one of the most meaningful days of my life. I have been living in a personal and mental incarceration ever since the day that I accepted the offer to work for a real estate mogul whose business acumen that I deeply admired."
That real estate mogul, of course, is Trump.
Michael Cohen is now addressing the court at his sentencing in Manhattan.
Cohen pleaded guilty in August to eight charges, including several counts of tax fraud and campaign finance violations. He also pleaded guilty last month to a charge of lying to Congress from Mueller's office.
Assistant US Attorney Nicholas Roos addressed the campaign-finance crimes, saying they carried a "tremendous societal cost."
Roos said "in committing these crimes, Mr. Cohen has eroded faith in the electoral process and compromised the rule of law."
Jeannie Rhee, with special counsel Robert Mueller's team, said Cohen has been honest.
"He has told the truth," she told the court.
Last week, the special counsel's team released a memo about Cohen saying he has cooperated with its inquiries.
After Rhee spoke, Assistant US Attorney Nicholas Roos addressed the court on behalf of the US Attorney's Office for the Southern District of New York.
"For all the hypothesizing that Mr. Petrillo has done, Mr. Cohen can’t have it both ways," he said, referencing Cohen's lawyer, Guy Petrillo's speech to the court. "There is a standard way this office conducts cooperation."
He added: "We’ve treated Mr. Cohen just the way we treat every other defendant that deal with the us attorney's office."
The Manhattan US attorney's office has asked for Cohen to receive a "substantial" sentence of roughly four years. However, Cohen and his legal team has asked for no prison time, citing his cooperation with multiple investigations — including the special counsel's Russia probe.
Michael Cohen's lawyer, Guy Petrillo, said Cohen has been treated unlike other defendants by prosecutors, noting that "Mr. Cohen had the misfortune to have been counsel to the President."
Cohen long served as the President's personal attorney and Trump's "fixer." Cohen even once boasted he would "take a bullet" to protect his longtime boss.
Petrillo, in court today, said Cohen wants to cooperate but that "he’s wary of a long term cooperation agreement."
"He wants both to remove himself and remove his family from the glare of the cameras," he said.
Michael Cohen's lawyer Guy Petrillo, addressing the court, said that his client "came forward to offer evidence against the most powerful person in our country," alluding to Cohen's testimony about President Trump.
Cohen, Petrillo said, couldn't "anticipate the full measure of attack that would be made against him" by both the President and "partisans and citizens who happen to be aligned with the President."
Petrillo said special counsel Robert Mueller's investigation into Russian interference in the 2016 election "is of utmost national significance, no less than seen 40 years ago in Watergate."
Petrillo also noted Cohen's actions "stand in profound contrast to the decision of some others not to cooperate and allegedly to double deal while pretending to cooperate."
CNN caught up with Michael Cohen's in-laws, Fima and Ania Shusterman, as they made their way to court this morning. Asked it they felt Cohen would be coming home today, they were doubtful.
CNN: Do you think he’ll be coming home today?
Shusterman: "I don’t think so."
Cohen pleaded guilty in August to two campaign finance violations tied to payments he made or orchestrated to women during the campaign to stay silent about alleged sexual encounters with Trump, five counts of tax fraud and one count of making false statements to a bank.
The Manhattan US Attorney's office has asked for Cohen to receive a "substantial" sentence of roughly four years.
