The purge of Department of Homeland Security leadership continued Tuesday with the resignation of Acting Deputy Secretary Claire Grady. This comes two days after Homeland Security Secretary Kirstjen Nielsen’s ouster and one day after Director of the Secret Service Randolph “Tex” Alles was removed from his position. Grady’s exit clears the path for Kevin McAleenan, head of Customs and Border Protection, to become the acting DHS secretary. The purging of high-ranking DHS officials is said to be part of Trump adviser Stephen Miller’s plan to steer the administration toward even more hard-line immigration policies.
