The will come in the next several weeks, The New York Times reported, citing senior administration officials. Still, The Times added that it is not clear whether Trump has approved the plan, which was devised by chief of staff John Kelly.
Under the plan, Sen. Tom Cotton (R-Ark.) would replace Pompeo as CIA chief once Pompeo moved to State.
Some administration officials had in the past suggested Tillerson could be replaced by U.S. ambassador to the U.N. Nikki Haley, but Pompeo has become the favorite to take the role due to his rapport with Trump, the report says.
Cotton is expected to take the CIA job if offered, according to the report. A spokeswoman for Cotton told The Times his focus is on serving Arkansas in the Senate.
Tensions between Trump and Tillerson have been brewing for months.
Earlier this year, Tillerson denied an NBC News report that top Trump administration officials, including Vice President Pence, had urged him not to step down from the State Department.”The vice president has never had to persuade me to remain as secretary of State because I have never considered leaving,” Tillerson said.
Tillerson at the time refused to directly address the report that he referred to Trump as a “moron,” saying that he would not “deal with petty stuff like that.”
Trump and Tillerson have also clashed over other issues.
In October, Trump rejected the idea of negotiating with the North Korean regime, saying he told Tillerson he is “wasting his time trying to negotiation with Little Rocket Man.”
“Save your energy Rex, we’ll do what has to be done!” Trump tweeted at the time.
Tillerson reportedly wanted to remain in his position until the end of the year “to retain whatever dignity he could,” according to The Times.
