Tensions are increasing between President Donald Trump and Secretary of State Rex Tillerson, according to a White House source.
The anonymous official spoke to Axios and alleged that Trump has been making critical comments about the former Exxon Mobil CEO.
"Rex just doesn't get it, he's totally establishment in his thinking," Trump allegedly remarked after a meeting on Afghanistan, Axios reported.
The story comes after Tillerson made comments on Aug. 27 in which he distanced himself from Trump's reaction to the violence in Charlottesville, Virginia.
"I don't believe anyone doubts the American people's values or the commitment of the American government, or the government's agencies to advancing those values and defending those values," Tillerson said on Fox News.
Responding to a follow-up question about Trump's values, Tillerson declared: "The president speaks for himself."
Asked about Tillerson's remarks on Aug. 28, a State Department spokesman reiterated that Trump speaks for himself "because the Constitution speaks for the country," according to CNN.
The aide stated that Tillerson's comments had not been intended as a criticism of Trump.
"The secretary and president have expressed different points of view," added the aide. "He isn't being critical, but more so re-establishing without confusion what are known American values."
This isn't the first time Trump and Tillerson have adopted opposing views. In June, when a Saudi Arabian-led alliance of Gulf states imposed a diplomatic blockade on Qatar, Trump backed the move while Tillerson urged restraint, appealing to the parties to engage in "calm and thoughtful dialogue," according to Axios.
Tillerson also met with the then-foreign minister of Venezuela as Trump was allegedly preparing to announce sanctions on the country.
A White House source told CNN that Trump is becoming frustrated with the way Tillerson is running the State Department. Some have criticized the secretary of state for failing to fill top positions in his department.
"He is in a tough spot. No doubt," the source told CNN.
But a White House official dismissed any suggestion that the relationship between the two men was breaking apart.
"Tillerson is a great representative for the administration and has confronted many diplomatic challenges well," the source told Axios.
Other top officials have expressed differences with Trump over his response to the Aug. 12 violence in Charlottesville, Virginia. According to Fox News, Gary Cohn, Trump's top economic adviser, was preparing to resign from the Trump administration. A source told Fox that Cohn had even drafted a resignation letter, but decided against stepping down after a meeting with the president.
