Some Trump advisers said they fear that Giuliani may have waived his right to assert that his conversations with the president are private — and that government or private lawyers pursuing lawsuits could now seek to interview him…

“The first rule is to shut up, which he is unable to do,” said Stephen Gillers, a law professor at New York University. “False exculpatory statements often come back to bite.”

“Giuliani’s barrage harmed his client,” he added. “He waived the privilege for communications with Trump on the subject of his public statements.”

One close Trump adviser agreed, saying Giuliani had “waived the privilege, big time,” with his public descriptions of his conversations with the president.
