U.S. deputy national security adviser for strategy Nadia Schadlow resigned from her position at the White House on Wednesday.
Schadlow is expected to leave the White House on April 27 after helping to assist with the transition.
Schadlow is the third security official to leave the White House since John Bolton replaced Gen. H.R. McMaster as national security adviser to President Donald Trump.
Homeland security adviser Thomas Bossert left his post Tuesday and National Security Council spokesman Michael Anton resigned Sunday.
Schadlow thanked Trump for “the opportunity to serve you and the American people” in her resignation letter obtained by CNN.
