Sen. Richard Blumenthal (D-CT) raised the alarm about the possibility of U.S. troop deployment to Iran after Secretary of State Marco Rubio briefed the Senate on the state of the conflict in the Middle East.

“I am more fearful than ever after this briefing that we may be putting boots on the ground and that troops from the United States may be necessary to accomplish objectives that the administration seems to have,” Blumenthal told reporters after the briefing.
