Lawyers for former Trump personal attorney Michael Cohen argued Friday that their client should not go to prison for the criminal charges to which he has pleaded guilty, and unequivocally linked much of his wrongdoing to his desire to protect and support President Trump.

In a late-night court filing, lawyers for the onetime Trump loyalist wrote that their client was a changed man who was eager to share his knowledge with law enforcement and mindful that he would have to ‘‘begin his life virtually anew.’’ Their filing detailed what they said was Cohen’s already extensive cooperation, including seven voluntary interviews with the team of special counsel Robert Mueller, as well as meetings with federal prosecutors in New York, representatives of the New York State Attorney General’s office, and officials with the New York State Department of Taxation and Finance, which are conducting wide ranging probes into Trump’s campaign and his family foundation.

Friday’s filing in no uncertain terms connected Cohen’s wrongdoing to Trump. Cohen’s lawyers asserted, for example, that Cohen paid off women to keep quiet about alleged affairs with the president to stop them from ‘‘disseminating narratives that would adversely affect the Campaign and cause personal embarrassment.’’ And they said Cohen lied about efforts to finalize a Trump business project in Moscow during the heart of the campaign because he knew it was Trump’s ‘‘strongly voiced mantra’’ to minimize the investigation into connections between his campaign and the Kremlin. In fact, lawyers for Cohen alleged that he and Trump discussed the possibility of Trump traveling to Russia in the summer of 2016.

A lawyer for Trump and a White House spokesman did not immediately return messages seeking comment Saturday. Trump this week accused Cohen of lying to spare himself time in prison — an allegation that is sure to be fueled by Cohen’s request for a punishment that includes no time behind bars.

Cohen had pleaded guilty in August to five counts of tax evasion, one count of making a false statement to a bank, and two campaign finance violations, admitting at that time he and the chief executive of a media company worked in the summer of 2016 to keep an individual from publicly disclosing information that could hurt Trump’s campaign. Two women had alleged extramarital affairs with Trump, which the president denies. On Thursday, Cohen added an additional guilty plea, admitting that he lied to Congress about an ultimately unsuccessful effort to build a Trump building in Russia. He is expected to be sentenced on Dec. 12, and prosecutors have yet to submit their own recommendation.

According to Cohen’s sentencing submission, federal sentencing guidelines in just the first case call for him to spend as many as five years and three months in jail. His lawyers, though, disputed those calculations and argued his remarkable, if out-of-the-ordinary, cooperation warranted a sentence of ‘‘time-served.’’

Cohen, unlike most defendants, did not enter into a traditional cooperation agreement so his sentencing would not be delayed, though he nonetheless met — and expected he would continue to meet — with law enforcement agencies that wanted to talk to him, his lawyers wrote. And he did so mindful of ‘‘regular public reports referring to the President’s consideration of pardons’’ and as Trump launched a ‘‘raw, full-bore attack’’ on the investigations which Cohen was aiding, they wrote.

The sentencing submission traced Cohen’s background and sought to downplay the non-Trump related charges to which Cohen pleaded guilty. But more notable than that were the allegations it leveled against the president.

Cohen’s lawyers argued both the campaign finance violations and the lies to Congress were a product of his ‘‘fierce loyalty’’ to Trump, whom they at times referred to as ‘‘Client-1,’’ adding that, ‘‘In each case, the conduct was intended to benefit Client-1, in accordance with Client-1’s directives.’’

‘‘Michael regrets that his vigor in promoting Client-1’s interests in the heat of political battle led him to abandon good judgment and cross legal lines,’’ Cohen’s lawyers wrote.
