Trump pick pulls nomination due to lack of Senate support after past comments

Republicans hold a 12-10 majority on the panel, meaning a single GOP defection would result in a tie vote and block the nomination from moving to the full Senate.

"Unfortunately, at this time this unanimous support was not forthcoming," Carl wrote, adding that he did not want the administration to "waste valuable time and energy" attempting to change the outcome.

Carl rejected that characterization, saying he is "not a White nationalist" and that his remarks referred to a broadly shared American culture that people of all backgrounds could embrace.

"Unfortunately, for senior positions such as this one, the support of the President and Secretary of State is very important but not sufficient," Carl added on X. "We also needed the unanimous support of every GOP Senator on the Committee on Foreign Relations, given the unanimous opposition of Senate Democrats to my candidacy, and unfortunately, at this time this unanimous support was not forthcoming."

"I remain extremely confident in President Trump, Secretary Rubio, and the rest of the outstanding team at State (a group of leaders that includes many close friends)," Carl concluded on X. "I know they will continue to pursue a foreign policy that puts America first, and that they will work to ensure America is able to exercise its power and influence in the world like never before."

Fox News Digital reached out to the White House and the State Department for comment and has not heard back.
