Zbigniew Brzezinski, national security adviser to former President Jimmy Carter, has died.

His daughter Mika, co-host of MSNBC’s “Morning Joe” made the announcement late Friday in a post on Instagram. “My father passed away peacefully tonight. He was known to his friends as Zbig, to his grandchildren as Chief and to his wife as the enduring love of her life,” she wrote. “I just knew his as the most inspiring, loving and devoted father any girl could ever have.”
