CNN quoted US President Donald Trump as saying that "the Saudis have betrayed his confidence" and that he is disturbed by the murder of Saudi journalist Jamal Khashoggi.
Trump told Saudi officials he was blaming them for making him look bad, the channel said.
"President Trump's use of the word treason is important," Edwards Joseph, executive director of the Institute for International Affairs in Washington, said in a statement to the island. "Treason is a powerful word. It was used by senior officials like Sen. Lindsey Graham, who was a supporter of Saudi Arabia and used this phrase to express his feelings. About what the Saudis did and their attempt to cover up the crime. "
"This position is an expression of the White House that they are concerned about the assassination of Khashoggi, and they intend to hold the Saudis accountable for this."
The US researcher suggested that CIA Director Gina Haspel had returned from Turkey with "convincing" evidence that the White House had changed its position.
President Trump said earlier that he was not satisfied with what he heard from the Saudi side about the killing of the Saudi journalist.
Trump said he spoke with Crown Prince Mohammed bin Salman, and pointed out that the deadline of the month that the Saudis had requested was "very long and unjustified, and should expedite their investigations," pointing out that he will know all the details of his staff who went to Riyadh and Ankara.
Trump, who is resisting the pressure to stop arms sales to Saudi Arabia, has declined to say Riyadh's account of the incident is "trustworthy" and returns last Sunday to "lies" in Riyadh's account of the case.
Trump described Khashoggi's killing as "stupid and stupid" and said he would be "very upset" if the king and his crown prince were involved in the operation.
