President Donald Trump has lost his longtime national security aide, Robert Gabriel, who is departing the White House to pursue 'new chapters,' according to a post by Chief of Staff Susie Wiles.
Departure Announced by Chief of Staff
Wiles shared the news on X, expressing regret at his departure. 'Today is a day I hoped would not come,' she wrote, describing Gabriel as 'young, brilliant, and talented.' She noted that he is moving on to a new 'chapter' and highlighted his role as a 'trusted confidant' and 'dear friend.'
Gabriel, in his early 30s, served as principal deputy national security advisor under Secretary of State and National Security Advisor Marco Rubio. He worked for Trump for over a decade, starting in 2015, and was instrumental during the 2016 campaign, both terms, and the transition team.
Praise from Rubio
Secretary Rubio also congratulated Gabriel, stating, 'I am proud of the outstanding leadership Robert Gabriel has delivered as Principal Deputy National Security Advisor.' Rubio highlighted Gabriel's foreign policy expertise, government connections, and 'unmatched ability to solve complex problems,' which he said contributed to historic wins for the administration.
Gabriel joined the National Security Council shortly after Mike Waltz's departure in May 2025. A source close to him described him as someone who 'doesn't like the limelight' and helped run a 'leaner operation' at the NSC.
Background and Impact
Before his White House role, Gabriel worked as an associate producer at Fox News. He played a pivotal policy role during Trump's first 100 days, according to Wiles. A source close to the White House called his departure 'a huge loss,' noting that 'Susie and Gabriel are in lockstep - she doesn't do anything without him.' Another source deemed him 'irreplaceable.'
Gabriel's departure marks the end of a long partnership that began in 2015 and continued through multiple campaigns and terms. His next steps have not been disclosed.
