Elaine McCusker, a senior Pentagon official who questioned the legality of the Trump administration withholding military aid to Ukraine, is resigning, Defense Secretary Mark Esper announced Tuesday.
McCusker was appointed acting comptroller last July, and was later nominated to permanently take on the position. In March, the White House decided to withdraw her nomination, after emails were made public showing her concerns over the Ukraine aid. The hold on the aid was what led to President Trump being impeached earlier this year on charges that he abused his power.
In a statement, Esper said McCusker, whose resignation is effective June 26, "worked tirelessly to ensure that our budgeting and audit processes give full value to the taxpayer while meeting the enormous security needs of our nation as well as the men and women who serve it."
