Another senior Trump administration official is leaving the White House, Axios reported on Tuesday.

Emily Underwood, the top deputy to Deputy Chief of Staff Stephen Miller, is departing for Trust Ventures, a venture capital firm, where she will serve as a partner. Miller, a longtime Trump adviser who also held a senior policy role in the first Trump administration, helps steer the White House's policy agenda.

Underwood has served in the Trump administration throughout President Donald Trump's second term, which began in January 2025, according to Axios. Her work has focused on policy, including the implementation of a strategy across the federal government on nuclear energy research and development.

Her move adds another personnel change inside a White House that has relied heavily on senior aides who sit close to the center of policy development, making turnover in these roles closely watched for signs of continuity in implementation. Caleb Orr, a top adviser to Secretary of State Marco Rubio, will replace Underwood. Rubio, a former U.S. senator from Florida, now leads the State Department. Orr has worked closely with Rubio and has been described by Axios as a "key architect of the State Department's critical minerals, energy and commercial diplomacy policies."

News of Underwood's departure set off fireworks on social media.

"It's a sinking ship," Democratic strategist Mike Nellis posted on X.

"Rat flees sinking ship," Jason Tufele Carl Johnson, a former staffer for Rep. Raul Grijalva of Arizona, posted on X.
