Sen. John McCain (R-Ariz.), the chairman of the Armed Services Committee, who was recently diagnosed with brain cancer and made a triumphant return to Washington, D.C. to be a part of the health care debate, said in a release that Trump's directive was "unclear" and "inappropriate," given the Pentagon's study on the issue, according to Reuters. He added that he doesn't believe the new policy is appropriate without proper vetting from the Secretary of Defense, ranking military officials and the Congress.
