Attorney General William P. Barr has told people close to President Trump — both inside and outside the White House — that he is considering quitting over Trump’s tweets about Justice Department investigations, three administration officials said, foreshadowing a possible confrontation between the president and his attorney general over the independence of the Justice Department…

“He has his limits,” said one person familiar with Barr’s thinking, speaking on the condition of anonymity, like others, to discuss internal deliberations…

The standoff between Trump and Barr intensified Tuesday when Trump declared in a string of early morning tweets that he might sue those involved in the special counsel investigation into his 2016 campaign and suggested that Roger Stone, his friend convicted of lying to Congress in that probe, deserved a new trial.

Hours later, a Justice Department official said prosecutors had filed a sealed motion in court arguing the opposite and that they had Barr’s personal approval to do so.
