Former US Secretary of State Rex Tillerson has told a congressional committee that President Donald Trump's son-in-law conducted foreign policy behind his back.
Former US secretary of state Rex Tillerson has cited an awkward encounter with President Donald Trump's son-in-law in a Washington restaurant as an example of diplomacy being conducted behind his back when he was in the administration, according to a transcript of a congressional hearing.
Tillerson, who was fired by Trump in March 2018, mentioned the story during a day of closed-door evidence before the House Foreign Affairs Committee about his rocky, 13-month tenure as secretary of state.
He described his surprise to find that he happened to be dining in the same restaurant while Jared Kushner and Mexican secretary of foreign affairs Luis Videgaray had a private meal.
The former top US diplomat and chief executive of ExxonMobil said he "could see the colour go out" of the Mexican official's face when Tillerson greeted them at their table with a smile.
"And I said: 'I don't want to interrupt what y'all are doing'," Tillerson recalled for the committee.
"I said 'Give me a call next time you're coming to town'. And I left it at that."
The White House declined to comment on Tillerson's depiction of Kushner's activities.
Trump had harsh words for his former top diplomat in December after Tillerson said in rare public remarks that the president was "undisciplined" and did not like to read briefing reports.
Trump called him "dumb as a rock" in a tweet.
Tillerson described the restaurant incident as an example of one of the "challenges" he faced during his 13-month tenure as secretary of state that ended when Trump abruptly fired him over social media.
He said it was a "unique situation" to have the president's son-in-law as a White House adviser, saying "there was not a real clear understanding" of the diplomatic role.
Tillerson said there other examples.
He noted Kushner "met often" with Mohammad bin Salman, the crown prince of Saudi Arabia, and that the president's son-in-law requested that the secretary meet with an official from the kingdom to discuss a document they had been developing that was "kind of a roadmap" for the future of the relationship between the two countries.
The foreign trips raised concerns, the former secretary said, because Kushner would not co-ordinate with the State Department or the local embassy in the countries he visited.
Tillerson said he raised the issue with him but "not much changed".
Tillerson, accompanied by a personal lawyer and a State Department lawyer, gave evidence in private last month to the committee.
A transcript was released on Thursday.
There were large sections redacted, including some where he discusses issues related to an Oval Office meeting that involved the Russian foreign minister Sergey Lavrov and ambassador Sergei Kislyak.
He was prohibited from discussing private conversations with Trump and avoided certain highly publicised incidents, including reports he once referred to the president as a "moron".
He told the committee he had never met Trump before being urged by him to take the job and he was "stunned" by the offer after his long career as an oil industry executive with extensive overseas experience, especially in Russia and the Middle East.
Tillerson, who had been acquainted with Russian President Vladimir Putin since the late 1990s, said he told the leader during his first visit as secretary of state that relations with the US were bad but could be improved if they worked to build trust.
"I said the relationship is the worst it's been since the Cold War but I looked him in the eye and I said but it can get worse and we can't let that happen," he said.
