Colorado Sen. Cory Gardner, a Republican on the Foreign Relations Committee running for reelection in a state that Trump lost in 2016, commended “the administration for taking this decisive action.” But Gardner went on to urge the administration “to be prepared for possible retaliation … and to consult closely with Congress on any next steps should the situation escalate.”

Hillary Clinton won Colorado by 5 percentage points in 2016 and Inside Elections with Nathan L. Gonzales rates the Colorado Senate race a Toss-Up. Maine Sen. Susan Collins, the other GOP senator running in a state Clinton won, did not immediately comment on the strike.

Arizona GOP Sen. Martha McSally, an Air Force veteran and a member of the Armed Services Committee, also did not mention Trump by name. Trump carried Arizona by 3 points in 2016, but McSally lost her bid for the Senate in 2018. She was appointed after the election to fill the vacancy caused by Sen. John McCain’s death, and now is running for the remaining two years of that term. Inside Elections rates that race a Toss-Up.
