"Just because you can sing, though, doesn’t mean you should sing," Kennedy said.

"This is a case where tweeting less would not cause brain damage," he added.

Kennedy said Trump put Barr in an “awkward spot” when he tweeted about Stone’s case, adding the attorney general is “tough as a boot.”

“While the attorney general and others were trying to get the sentencing recommendations straight, the president tweeted, put the attorney general in an awkward spot, and he spoke out,” he said.

Justice Department prosecutors recommended a seven- to nine-year sentence for Stone, who was convicted of lying to Congress and witness tampering. But after Trump tweeted that the recommendation was unfair, the department announced that it wanted a shoter sentence, prompting the entire prosecution team to withdraw from the case.

Democrats have accused Barr of working on the president’s behalf to protect one of his associates.
