Rosenstein seemed surprised by the questions, the source confirmed.
CNN, which first reported the story, said the December meeting occurred as Rosenstein prepared to testify before the House Judiciary Committee.
During that hearing, he was asked: "Is it ever appropriate for a president of the United States to demand a Department of Justice official or FBI director to take a loyalty pledge?"
Rosenstein replied: "I don't have any opinion about that. Nobody has asked me to take a loyalty pledge other than the oath of office."
The White House and Justice Department declined to comment.
