Interior Secretary Ryan Zinke, facing federal investigations into his travel, political activity and potential conflicts of interest, will be leaving the administration at year's end, President Donald Trump said Saturday. In his resignation letter, obtained by The Associated Press, Zinke said "vicious and politically motivated attacks" against him had "created an unfortunate distraction" in fulfilling the agency's mission.
Trump, in tweeting Zinke's departure, said the former Montana congressman "accomplished much during his tenure" and that a replacement would be announced next week. The Cabinet post requires Senate confirmation.
Zinke is leaving weeks before Democrats take control of the House, a shift in power that promises to sharpen the probes into his conduct.

His impending departure comes amid sweeping changes in the Trump administration. The president made a similar announcement about Chief of Staff John Kelly and said budget director Mick Mulvaney would serve as acting chief of staff. It was not immediately clear who would then replace Mulvaney or why Mulvaney was chosen for the job.
Attorney General Jeff Sessions resigned Nov. 7, the day after the midterm elections, at the request of the president. The head of the Environmental Protection Agency, Scott Pruitt, resigned under tremendous pressure after reports of multiple ethics investigations into his misuse of taxpayer funds.
Zinke's resignation letter, obtained from a Zinke aide on Saturday, cites what he calls "meritless and false claims" and says that "to some, truth no longer matters."
The letter, dated Saturday, said Zinke's last day would be Jan. 2. It was not clear whether Zinke had already submitted the letter when Trump tweeted.
Zinke, 57, played a leading part in Trump's efforts to roll back federal environmental regulations and promote domestic energy development. He drew attention from his first day on the job, when he mounted a roan gelding to ride across Washington's National Mall to the Department of Interior.
Zinke had remained an ardent promoter of both missions, and his own macho image, despite growing talk that he had lost Trump's favor. On Tuesday, Zinke appeared on stage at an Environmental Protection Agency ceremony for a rollback on water regulations. Mentioning his background as a Navy SEAL at least twice, he led the audience in a round of applause for the U.S. oil and gas industry.
Trump never established a deep personal connection with Zinke but appreciated how he stood tall against criticisms from environmental groups as he worked to roll back protections. But the White House concluded in recent weeks that Zinke was likely the Cabinet member most vulnerable to investigations led by newly empowered Democrats in Congress, according to an administration official not authorized to publicly discuss personnel matters who spoke on condition of anonymity.
His tenure was temporarily extended as Interior helped with the response to California wildfires and the West Wing was consumed with speculation over the future of chief of staff John Kelly. But White House officials pressured him to resign, the official said, which he did after his final public appearance at his department's Christmas party on Thursday night.
As interior secretary, Zinke pushed to develop oil, natural gas and coal beneath public lands in line with the administration's business-friendly aims. But he has been dogged by ethics probes, including one centered on a Montana land deal involving a foundation he created and the chairman of an energy services company, Halliburton, that does business with the Interior Department.
Investigators also are reviewing Zinke's decision to block two tribes from opening a casino in Connecticut and his redrawing of boundaries to shrink a Utah national monument. Zinke has denied wrongdoing.
The Associated Press reported last month that the department's internal watchdog had referred an investigation of Zinke to the Justice Department.
Zinke's travels with his wife, Lola Zinke, also had come under scrutiny.
Interior's inspector general's office said Zinke allowed his wife to ride in government vehicles with him despite a department policy that prohibits nongovernment officials from doing so. The report also said the department spent more than $25,000 to provide security for the couple when they took a vacation to Turkey and Greece.
Trump told reporters this fall he was evaluating Zinke's future in the administration in light of the allegations and offered a lukewarm vote of confidence. Zinke in November denied he already was hunting for his next job.
"I enjoy working for the president," he told a Montana radio station. "Now, If you do your job, he supports you."
"I think I'm probably going to be the commander of space command," Zinke said. "How's that one?"
Zinke outlasted EPA chief Scott Pruitt, another enthusiastic advocate of Trump's business-friendly way of governing who lost favor with Trump amid ethics scandals. Pruitt resigned in July. Trump's first Health and Human Services secretary, Tom Price, also resigned under a cloud of ethical questions.
Democratic leaders in Congress were scathing in response to the news that Zinke was leaving as well.
"Ryan Zinke was one of the most toxic members of the cabinet in the way he treated our environment, our precious public lands, and the way he treated the govt like it was his personal honey pot," Senate Minority Leader Chuck Schumer of the New York tweeted Saturday. "The swamp cabinet will be a little less foul without him."
House Minority Leader Rep. Nancy Pelosi, who is set to become speaker in January, said Zinke had "been a shameless handmaiden for the special interests" and his "staggering ethical abuses have delivered a serious and lasting blow to America's public lands, environment, clean air and clean water."
Arizona Rep. Raul Grijalva, the top Democrat on the House Natural Resources Committee, had warned that after Democrats took control of the House they intended to call Zinke to testify on his ethics issues.
Grijalva spokesman Adam Sarvana said Saturday that committee leaders still intended to ask for Zinke's testimony. "It's safe to say that Citizen Zinke may be leaving, but real oversight of former Secretary Zinke has not even started," Sarvana said in an email.
Earlier this month, ZInke unleashed a jarring personal attack on Grijalva, tweeting, "It's hard for him to think straight from the bottom of the bottle."
Zinke got a warmer send-off from Republican Sen. Lisa Murkowski of Alaska, head of the Energy and Natural Resources Committee, who said in a statement that he had been a "strong partner for Western states."
Under Zinke's watch, the Interior Department moved to auction off more oil leases, ended a moratorium on new sales of federally owned coal, and repealed mandates governing drilling. Zinke's focus on the president's energy agenda was cheered by oil, gas and mining advocates, who credit the administration with seeking to balance conservation with development on public lands. But his tenure was denounced by most conservation groups.
"Zinke will go down as the worst Interior secretary in history," said Kieran Suckling, executive director of the Center for Biological Diversity, in a statement released Saturday. "His slash-and-burn approach was absolutely destructive for public lands and wildlife. Allowing David Bernhardt to continue to call the shots will still be just as ugly. Different people, same appetite for greed and profit."
Bernhardt, the deputy secretary, is in line to lead the Interior Department on an interim basis. He has spent years in Washington, D.C., as a lobbyist for the oil and gas industry and has deep ties to Republican politicians and conservative interest groups.
An Idaho Republican, Rep. Raul Labrador, was interested in the job and planned to go to the White House on Saturday to discuss it with officials there, said a GOP congressional aide who spoke on condition of anonymity to describe Labrador's private plans.
Labrador, 51, is a member of the conservative House Freedom Caucus. He's retiring from Congress after eight years following his losing a bid for his state's GOP gubernatorial nomination last spring.
As head of Interior, Zinke made plans to realign the agency's bureaucracy, trimming the equivalent of 4,600 jobs, about 7 percent of its workforce. He also proposed a massive overhaul that would have moved decision-making out of Washington, relocating headquarters staff to Western states at a cost of $17.5 million.
Zinke was a one-term congressman when Trump selected him to join his incoming Cabinet in December 2016.
An early Trump supporter, Zinke is close to the president's eldest son, Donald Trump Jr., and publicly expressed his interest in a Cabinet post when Trump visited Montana in May 2016.
