The Senate Foreign Relations Committee said Wednesday it will hold hearings to review President Trump’s power to start a nuclear war. The committee’s chair, Republican Sen. Bob Corker, says next week’s hearing will be the first time since 1976 that the House or Senate has examined the president’s authority to launch a nuclear first strike. The planned hearings come after Sen. Corker repeatedly questioned whether Donald Trump is mentally fit to be president. Trump has repeatedly threatened to “totally destroy” North Korea and to unleash “fire and fury” on the nation of 25 million people.
