'It’s chilling': Trump's loyalists 'deeply alarmed' following latest attack on Jeff Sessions

President Donald Trump's decision to publicly attack his own attorney general this week is reportedly sending shock waves through the White House, even among the president's most loyal supporters.

Sources tell CNN that Trump's rebuke of Attorney General Jeff Sessions for recusing himself from the Russia probe "is causing deep alarm inside the West Wing, leading some to worry that their loyalty to Trump might not be reciprocated from the man in the Oval Office."

"It's chilling," one White House official told CNN.

Another White House official said that Trump's attack was particularly jarring because Sessions has been one of the president's most loyal cabinet members.

"No one was more loyal than Sessions," the official emphasized. "No one."

Sessions, who was the first Republican senator to officially endorse Trump's candidacy, got chastised by Trump during an interview with the New York Times on Wednesday.

"Sessions should have never recused himself and if he was going to recuse himself he should have told me before he took the job and I would have picked somebody else," Trump told the paper. "How do you take a job and then recuse yourself? If he would have recused himself before the job, I would have said, 'Thanks, Jeff, but I'm not going to take you.' It's extremely unfair -- and that's a mild word -- to the President."
