Executive privilege has been upheld since the presidency of George Washington. High level meetings between national leaders sometime require privacy. Foreign diplomacy is at danger of being politicized by political opponents. That said, I’d love to see transcripts of some of Obama’s visits with foreign leaders. You know. Like the time he told Medvedev he would have “more flexibility” in his second term. Encroaching on executive privilege for this president puts ALL future presidents of both parties at risk of political intrusion.
