Former Secretary of State Henry Kissinger is quite the social butterfly these days.

Back in January, the 89-year-old statesman honored his former boss, the late President Richard Nixon, at an event at the Mayflower Hotel celebrating the 100th birthday of the controversial president.

On Wednesday night, Kissinger will present Brent Scowcroft with the National Defense University Foundation’s first International Statesman and Business Advocate Award.

Scowcroft served as national security adviser under Presidents Gerald Ford and George Bush. He and Zbigniew Brzezinski, the national security adviser for President Jimmy Carter, have long worked together to advocate greater bipartisanship in U.S. foreign policy.

Also expected to attend the event tonight: Gen. Colin Powell, J.W. “Bill” Marriott, Sen. John McCain, R-Ariz., among other notables.
