Trump 'gets to hire and fire under the constitution' -McConnell
"He has the full authority to hire and fire under the constitution anybody in the executive branch. They all serve at the pleasure," said McConnell.
Trump on Monday defended his decision to fire the State Department's inspector general, Steve Linick, saying Secretary of State Mike Pompeo asked him to do so.
Democratic lawmakers said on Monday Trump might have fired the watchdog because he was investigating U.S. military sales to Saudi Arabia.
Congressional aides have also said Linick was probing whether Pompeo misused a taxpayer-funded political appointee to perform personal tasks for himself and his wife, such as walking their dog.
