Former Ambassador to Germany and Acting Director of National Intelligence, Richard Grenell, is widely regarded as the frontrunner for National Security Adviser in Trump’s second term. Known for his loyalty and strong alignment with Trump’s policies, Grenell has earned the trust of the former president's inner circle.

Other potential candidates include Keith Kellogg, a retired three-star Army general who served as National Security Adviser to former Vice President Mike Pence; Elbridge Colby, a former Pentagon official; and Robert O’Brien, Trump’s final National Security Adviser during his first term.
