President Joe Biden has nominated Mark Brzezinski to serve as his ambassador to Poland.

Playing a prominent role in American foreign policy, Scowcroft served as national security adviser to Presidents Gerald Ford and George H.W. Bush, the only national security adviser to two different administrations. He served as national security adviser to Bush, by then a close friend, during the four years of the Bush administration, 1989-93. A year later he became deputy assistant for national security under Henry Kissinger, Nixons national security adviser. He accepted a return engagement as national security adviser when he realized he would be at the presidents side instead of running the massive bureaucracy at the Defense Department.
