Senator Jeff Flake has said he is not interested in being reappointed by President Donald Trump.
The Arizona Republican has made clear his intention to retire after his term ends next year.
He will remain in the Senate as a Republican.
President Trump has called Flake a “total lightweight” and “a very nice guy”, and has publicly mocked him.
He has also publicly questioned Flake’s integrity.
But Flake has been a vocal critic of Trump’s foreign policy, including his decision to end the Iran nuclear deal and a US-led coalition in Syria, which he said cost lives.
Flake said he would not consider leaving office and had made clear that he would seek the Republican nomination in 2020.
Flake told reporters at a news conference at the White House on Thursday that he had no plans to step down from his job in the next year and that he is willing to serve in the new administration.
“I will continue to represent the people of Arizona as I have since January.
I am committed to that for the next four years.
I will continue fighting for Arizona.
I don’t plan to retire from the Senate,” he said.
Senator Jeff Flake on Trump’s presidency and his decision not to recuse himself from Russia investigation: “I have a very good relationship with President Trump and I have a good relationship, I am going to continue to do so.”
Floor: Trump’s ‘bad instincts’ are undermining US policy in Syria and Iran article A US Senate committee is considering a measure that would require the president to recusal if he determines he is acting in a way that threatens national security.
The measure, which is not yet officially a bill but has been referred to the Senate Judiciary Committee, would bar the president from acting on matters that could endanger the national security of the United States, and requires a finding that the president is acting as a surrogate for Russia, Iran or North Korea.
“I am concerned that Donald Trump has his bad instincts out on the world stage, that he has been unable to balance a desire to win and preserve his own presidency with his duty to protect the country, which we all know is paramount,” said Senator Richard Blumenthal, a Connecticut Democrat.
Blumenthal, who has been an outspoken critic of the Trump administration, said he was “not persuaded” by Trump’s explanation for not recusing himself from investigations into the Trump campaign’s ties to Russia.
It is unclear how the measure would be voted on.
