Secret Service chief out in latest high-level departure from Trump's White House

The director of the U.S. Secret Service is leaving his position, the White House said on Monday, but the outgoing head of theagency that provides protection for U.S. President Donald Trump and other topofficials insists he wasn't fired.

Randolph "Tex" Alles said on Monday that he was not fired, describing the shift as part of an "orderly transition in leadership" across the Department of Homeland Security, despite earlier reports citing administration officials who said he was being removed from his position.

"No doubt you have seen media reports regarding my 'firing.' I assure you that this is not the case, and in fact was told weeks ago by the administration that transitions in leadership should be expected across the Department of Homeland Security," Alles said in a message to Secret Service agents.

"The president has directed an orderly transition in leadership for this agency and I intend to abide by that direction," Alles said.

The announcement of his departureon Monday comes a day after Homeland Security Secretary Kirstjen Nielsen resigned.The Secret Service director reports to the Homeland Security secretary.

White House spokesperson Sarah Sanders said James Murray, a career Secret Service agent, would take over the Secret Service in May. Alles had run the agency for two years and served in the U.S. Marine Corps for 35 years before retiring as a major general in 2011.

The Secret Service is responsible for protecting senior U.S. officials including the president and vice president, former presidents and visiting heads of state.

The agency came under scrutiny last week after a Chinese woman carrying electronic devices was charged with bluffing her way through security checks at Trump's Mar-a-Lago resort in Florida.

Chuck Schumer, the top Democrat in the Senate, called for Alles to testify before Congress "as soon as possible about the potential security vulnerabilities at Mar-a-Lago and other counterintelligence and national security threats."

The series of sudden changes at DHS also raised eyebrows with some Republican leaders in the Senate.

"We are dealing with a humanitarian and security crisis at the border because Congress failed to act," said Ron Johnson, the chairman of the Senate Homeland Security committee.

"In addition to congressional dysfunction, I am concerned with a growing leadership void within the department tasked with addressing some of the most significant problems facing the nation."

The White House did not respond to requests for comment on the overhaul of the department.

List of departures grows

The Alles announcement marked the latest in a long line of firings, resignations and departures of senior officials in the Trump administration, a list that has included the secretaries of state, defense, homeland security, interior, veterans affairs and health and human services, the attorney general and numerous senior White House aides.

The first sign of Trump's overhaul of Homeland Security came late on Thursday, when he abruptly pulled his nomination of Ron Vitiello as director of U.S. Immigration and Customs Enforcement, part of DHS.

Trump described that move as part of a policy change "going in a tougher direction."

The Republican president, seeking re-election in 2020, has taken a hard line on immigration since taking office in January 2017, and he has said he will make border security a central theme in next year's race.

His first Homeland Security secretary was John Kelly, who later became his chief of staff. Kelly and Trump had an often-difficult relationship. Nielsen had been an aide to Kelly.

Nielsen, who oversaw Trump's bitterly contested immigration policies during her tumultuous 16-month tenure, resigned amid a surge in the number of migrants at the border with Mexico.

Her departure had been long rumored particularly after criticism of the administration's 2018 family separation policy at the border with Mexico and as U.S. border officials estimated that 100,000 migrants were apprehended at the southern border in March, the highest level in a decade. Trump was so frustrated about the increase that he announced he would cut off U.S. aid to Guatemala, Honduras and El Salvador.

A senior administration official said Trump asked for Nielsen's resignation when the two met at the White House on Sunday. Trump also announced that Kevin McAleenan, the U.S. Customs and Border Protection commissioner, would become acting DHS secretary.

CNN reported that Trump in recent weeks empowered his hard-line conservative aide Stephen Miller to lead the administration's border policies, and reported that L. Francis Cissna, director of the U.S. Citizenship and Immigration Services agency, and department General Counsel John Mitnick were also expected to soon leave their positions.
