Baker holds the distinction of being the only official to serve concurrently as Deputy National Security Advisor to the President and National Security Advisor to the Vice President during the second Trump administration. His tenure involved crafting the administration's National Security Strategy and navigating major diplomatic initiatives. Before his time in the White House, he served as a career Foreign Service Officer with assignments in Afghanistan and at NATO headquarters in Brussels.

At American Global Strategies, founded by Robert C. O'Brien and Alexander B. Gray, Baker will provide counsel on geopolitical strategy and the intersection of global security and corporate investment. O'Brien noted that Baker’s arrival comes at a time when international instability is increasingly dictating market conditions. Baker, who earned his doctorate at the University of Oxford, will work directly with the firm’s leadership to guide corporate clients through volatile policy landscapes.
