In a meeting with Trump lawyers in March this year, Muller warned that such a move could take action. He also said that the trump will be forced to appear before the investigating officer.
Trump's former lawyer John Dowd said this on Tuesday. The Washington Post, the first publication of the news of Muller's summons, was first published.
It is believed that Muller was the first to say that the arrangement for the trump to testify was for the first time.
The Washington Post reported that the president had no obligation to face the investigation of the central investigating officers in Russia, insisting that the Trump lawyers had stressed the meeting.
But Muller's team officials will then issue an affidavit against the president when the Trump prompted him to face the investigation. They also agreed to give more specific information to the lawyers about the kind of questions the President would ask.
Trump's lawyer, John Dowd, resigned in almost a half-a-week meeting in March. He said that the investigation of Russian intervention in US presidential elections was not 'boys'.
"You are interrupting the work of the President of the United States," said Doug, for the investigation officers at the time that said.
After the information provided by the team of Muller, Trump lawyer J Secoulo made a list of the possible questions that may be encountered. There were 49 questions in this list.
The list first appeared on Monday in The New York Times. Whether there was any procession of Trump's campaign camp with Russia in many questions, whether Trump tried to prevent illegal investigation of Russia, what is the purpose of the trump to dismiss former FBI director James Komiki? There were also questions about this.
Troubled by a tweet on Tuesday, Trump has termed the leakage in the media as 'disgraceful'. His lawyer said on Tuesday evening, "We do not discuss the conversation with the Special Counsel Müller's office."
However, The New York Times says that the list of questions from other people was found, not the president's lawyer.
White House spokesman Raj Shah said the New York Times report is "faulty."
In a tweet on Tuesday, Trump criticized the press leaks in the media and said there is no question of collusion with Russia. He also said that it is very difficult to stop the crime that has not happened.
The team led by Müller is investigating whether to intervene in Russian presidential elections in 2016. They are also investigating the potential involvement of the camp with the Kremlin campaign and whether the tram in the FBI investigation has been blocked illegally.
Muller was appointed as a special prosecutor in May last year after the FBI's director James Komie dismissed the trump. Comami alleged that the trump promptly dismissed him for investigating Russian intervention in the elections.
Trump has been denying Moscow's involvement with his camp in the election campaign since the beginning.
Although the Republican is one of the main targets of the investigation, Muller told his lawyer in March that the investigation was not underway to make him a criminal.
It is not known when Muller wants to meet the president in the investigation.
Trump had once said that he himself was willing to talk to Muller. But after the investigation of Trump's private attorney's office, his enthusiasm has been very low, CNN said.
