The Washington Post quotes US officials that Justice Secretary William Barr told close associates of President Donald Trump that he may resign if the president continues to tweet about his department's investigations into his friend.
Barr said last week that Trump's tweets made it impossible for him to carry out his duties as minister, and asked him to stop writing tweets that dealt with issues before the court.
He added - in an interview with "ABC" - that the president's attack on the prosecution team charged with the case of Roger Stone (Trump's close friend) is harmful to the judicial system and the Ministry of Justice.
Commenting on Barr's remarks, White House spokeswoman Stephanie Grisham said the president had full faith and confidence in the justice minister to do his job and strengthen the rule of law.
She added in a statement issued by her that the president was not at all troubled by the comments of the Minister of Justice, who has the right - like any citizen - to express his views publicly.
Barr was heavily criticized after he interfered in the Stone case, who was convicted on seven charges, including lying to Congress. Prosecutors recommended that he be imprisoned for between seven and nine years.
After Trump's anger in which he condemned the original recommendation for a sixty-year prison sentence of sixty and considered it very harsh, the ministry canceled the prosecution and requested a "much lesser" prison sentence which prompted the four prosecutors to resign from the case, in a clear protest.
In a statement, a number of Republican leaders in Congress announced their support for the Attorney General in facing what he called an attack on him.
Republican leaders said Barr is committed to the rule of law and the constitution, and enjoys the trust of the people.
Barr had denied on ABC News that the president had asked him to interfere in the Stone case.
He indicated that no one would accept bullying and try to influence it, be it from Congress, the press, or the president.
