US President Donald Trump is not worried about the comments of Attorney General William Barr about his tweets, said White House spokeswoman Stephanie Grisham, Daily Mail reported.

"The president wasn’t bothered by the comments at all and he has the right, just like any American citizen, to publicly offer his opinions," White House press secretary Stephanie Grisham said to Fox on Thursday. 

Earlier, Barr noted that he "cannot do my job here at the department with a constant background commentary that undercuts me."
