Vice President JD Vance is adding another national security adviser to his team at a moment when the administration is grappling with mounting global crises.
Vance has tapped Cliff Sims, a long-time ally of President Donald Trump, for the role. Sims will serve alongside Andy Baker, who currently splits his time between the National Security Council and the Office of the Vice President. Together they will expand Vance’s foreign policy operation at a critical juncture for the administration, which is involved in multiple conflicts abroad including the war between Russia and Ukraine and the war with Iran, which has proven difficult to contain.
