Supreme Court Justice John Roberts has been left “shaken” by the unexpected public reaction to his ruling in the Donald Trumppresidential immunity case, a columnist wrote Friday.

Slate’s judicial writer Dahlia Lithwick wrote that Roberts was left shocked that Americans didn’t buy his attempt to persuade them that his ruling was not about Trump, but instead focused on the office of the presidency. The court ruled that a president was largely immune from criminal prosecution for official actions.

Lithwick referenced a report by CNN’s Joan Biskupic. He “was shaken by the adverse public reaction to his decision affording [Donald] Trump substantial immunity from criminal prosecution," she wrote.

"His protestations that the case concerned the presidency, not Trump, held little currency.”
