U.S. Attorney General William Barr on Thursday pushed back against Donald Trump after the president's attacks on the prosecutors, judge and jury in the trial of a longtime adviser, saying Trump should stop tweeting about Justice Department cases and that he would not be "bullied" by anyone.

Barr, the top U.S. law enforcement officer, said in an ABC interview that Trump's tweets "make it impossible for me to do my job."

A juror in the trial in which veteran Republican operative Roger Stone was convicted told Reuters that he was appalled by Trump's remarks.
