JUDY WOODRUFF:

And we turn now to our panel of former Justice Department officials.

George Terwilliger served as former deputy attorney general and acting attorney general under President George H.W. Bush. Walter Dellinger served in the Clinton administration as assistant attorney general and as acting solicitor general. And Carrie Cordero, she served in the Justice Department under presidents George W. Bush and President Obama, where she worked on matters of national security.

Now, before I speak with them, one issue today was former FBI Director Comey's testimony about a February meeting in the Oval Office, when everyone else left, and the president asked him to stay.

Democratic Senator Mark Warner today pressed the attorney general on that. Let's listen.
