This afternoon, the Washington Post broke a major story: Donald Trump disclosed highly classified material to the Russian ambassador and Foreign Minister in the Oval Office last week, compromising a highly sensitive counterterrorism program run by an allied intelligence service. This evening, we got former DNI General Counsel Robert Litt on the line for a discussion with Susan Hennessey and Benjamin Wittes of the latest mess. Litt helped coordinate and manage the intelligence community's response to the Edward Snowden revelations, so he knows a little something about responding to massive intelligence disclosures. We talked about how bad the disclosure may be, what the remedies for it are, and what we still don't know.
