President Donald Trump has picked Army Lt. Gen. H.R. McMaster to succeed Michael Flynn as his national security adviser, Trump said Monday. He made the announcement at Mar-a-Lago, flanked by McMaster and the acting adviser, retired Army Gen. Keith Kellogg. Kellogg will stay on as McMaster's chief of staff, Trump said. "He's a man of tremendous talent and tremendous experience," Trump said of McMaster. "He is highly respected by everybody in the military." The president, who has no military experience, has shown a preference for generals in the top security roles.
