Mr. Trump has been investigating Mr Flynn's investigation since at least the beginning of last year. In February 2017, alone in the Oval Office with the F.B.I. Director James B. Comey, the president, asked him to stop the investigation, Mr. Comey told the legislators. After this episode became known, Mr. Müller was appointed Special Adviser by the Ministry of Justice.
The day after Mr. Flynn pleaded guilty, the President wrote in a Twitter post written by Mr. Dowd. He blamed Mr. Flynn for allegations he made to the FBI but Mr. Trump defended his former national security adviser continued to publicize and said two days later that he felt "very bad" for Mr. Flynn and that the FBI had "destroyed his life".
. Manafort, who headed Mr. Trump's presidential campaign for several months, has been charged in dozens of cases with money laundering and other financial crimes related to his work as a lobbyist and former advisor to Viktor F. Yanukovych, who was at the time President of Ukraine. The charges are not related to any work Mr. Manafort has done for Mr. Trump.
Rick Gates, who was Mr. Manafort's business partner for many years and was also Deputy Chairman of Trump's presidential campaign, pleaded guilty to a cooperation agreement with Mr. Müller's team last month. On the day the declaration of consent was promulgated, Mr. Manafort promised to prosecute the charges against him.
A total of 19 people were charged with crimes by Mr Müller. Five of them, including Mr Flynn and two other Trump colleagues, have pleaded guilty and agreed to work with him.
In August, Mr. Trump pardoned Joe Arpaio, the former sheriff from Arizona, who had been convicted for criminal defiance of the state for refusing to ban Latinos from traffic jams and other prosecutions. The forgiveness aroused an outcry because Mr Arpaio, who had become a national symbol of conservative and liberal suppression of illegal immigration, had supported Trump's presidential election.
