April 9 (UPI) -- Acting Deputy Secretary of Homeland Security Claire Grady became the latest DHS official to resign on Tuesday night.
"For the last two years, Claire has served [DHS] with excellence and distinction," Nielsen wrote. "She has been an invaluable asset to DHS -- a steady force and a knowledgeable voice."
President Donald Trump announced Nielsen's resignation on Sunday and she agreed to stay on through Wednesday.
Grady's resignation will clear the way for Trump's selection Kevin McAleenan to lead the DHS.
