White House is discussing a plan to oust Secretary of State Rex Tillerson and replace him with CIA Director Mike Pompeo in a major shake-up of President Trump's national security team, administration officials said Thursday.

The move would put Pompeo, a former congressman who has grown close to Trump during his tenure atop the CIA, in charge of US diplomacy. Secretary Tillerson, the former Exxon Mobil chief executive officer, has had a rough first year characterized by tensions with Mr. Trump in several foreign policy areas and overwhelmingly negative publicity over Tillerson's planned overhaul of the State Department.

Republican Sen. Tom Cotton of Arkansas, one of Trump's staunchest defenders on foreign policy in Congress likely to fill vacancy in CIA . Senator Cotton's office wouldn't comment other than to say: "Senator Cotton's focus is on serving Arkansans in the Senate."

Tillerson's likely ouster loomed awkwardly over an Oval Office meeting Thursday between Trump and the visiting crown prince of Bahrain. Asked by a reporter whether he wanted Tillerson to stay on the job, "He's here. Rex is here," the president said.

A White House official said it was unclear how soon Tillerson might be replaced, and word of the plan appeared to catch Tillerson and his staff off-guard. Tillerson aides and the State Department did not immediately respond to requests for comment. The New York Times, which first reported the potential shake-up, said it was likely to happen within several weeks.

Nor was it clear whether either Pompeo or Cotton had been formally approached by the White House about the potential new roles. Yet several administration officials said that Pompeo has said in the past that he's open to taking the job.

White House spokeswoman Sarah Huckabee Sanders said there were no staffing changes to announce and hinted that Tillerson would likely remain at least until year's end.

"Secretary Tillerson continues to lead the State Department, and the entire Cabinet is focused on completing this incredibly successful first year of President Trump's administration," she said.

The White House started telling people in September that Tillerson would be replaced, said a senior administration official. By that point, some issues that needed sign-off from the secretary of state were being put off until after Tillerson was gone, said the official, who like others wasn't authorized to comment publicly and demanded anonymity.

Foreign leaders had anticipated Tillerson was likely to attend a scheduled gathering of NATO foreign ministers next week in Brussels, though the State Department hadn't confirmed that.

Secretary of State Rex Tillerson is expected to step down from his position in January, according to Fox News on Thursday.

Mike Pompeo, the current CIA director, could replace him -- leaving Sen. Tom Cotton, R-Ark., to possibly lead the CIA in Pompeo’s place, sources also said.

The news comes amid Tillerson’s contentious relationship with President Donald Trump. In October, NBC News reported that Tillerson considered resigning from his position last summer amid disputes with the White House. Additionally, Tillerson allegedly called the president as a 'moron' after a meeting with cabinet officials in October.
