Michael Cohen, a former attorney general of US President Donald Trump, said his job was to cover up his client's "dirty" actions, saying he was responsible for his crimes "including those that could implicate the president of the United States."

The statement came as he sought to ease his sentence on Wednesday before court judge William Bolley III before being sentenced to three years in prison.

Cohen's lawyers demanded that he not be jailed after pleading guilty to tax evasion, false testimony to a financial institution, illegal contributions to the presidential campaign and false testimony to Congress. Judge Polley was sentenced to three years in prison.

He also admitted he had paid a total of $ 280,000 to former playboy Playboy, Karen McDougall and porn actress Sturmie Daniels, for their silence after threatening to expose the relations they claimed to have established with Trump during the campaign.

US lawyer admitted last month that he had lied to Congress about his contacts with Russia over the construction of the Trump Tower in Moscow.

Cohen, 52, is a member of the Trump campaign team charged with breaking the law, but he is the only one from the nearby Trump circle. For 12 years, he served as vice president of the Trump organization, which includes real estate businesses associated with TRMP, where the lawyer is one of his closest associates.
