Acting Homeland Secretary Chad Wolf will be resigning by the end of Monday, he said, citing recent court rulings over his appointment.
"Effective at 11:59 p.m. today, I am stepping down as your Acting Secretary. I am saddened to take this step, as it was my intention to serve the Department until the end of this Administration," he wrote in an email to the department, the DHS confirmed to The Epoch Times.
"Unfortunately, this action is warranted by recent events, including the ongoing and meritless court rulings regarding the validity of my authority as Acting Secretary," he added. "These events and concerns increasingly serve to divert attention and resources away from the important work of the Department in this critical time of a transition of power."
Pete Gaynor, the administrator of the Federal Emergency Management Agency (FEMA), will be acting secretary, Wolf wrote.
"Serving the Department and leading the finest public servants in the federal government has been the honor of a lifetime," he wrote. "I did not seek this responsibility but answered the call to service as each of you have during your careers."
In his letter he reflected on accomplishments the DHS has overseen in the past several years.
"Together, we have strengthened border security, reformed our immigration system, stood up a world class cybersecurity agency, increased the worldwide aviation security baseline, enhanced US Coast Guard readiness, countered malign nation-state influence, responded to countless natural disasters, highlighted the vital work of the Federal Protective Service, supported the security for multiple federal and state elections, and continue to respond to a global pandemic."
Wolf expressed confidence in the next four years.
"I leave knowing that the Department has positioned itself for an orderly and smooth transition to President-elect Biden's DHS team," he wrote. "Welcome them, educate them, and learn from them. They are your leaders for the next four years—a time which undoubtedly will be full of challenges and opportunities to show the American public the value of DHS and why it is worth the investment."
