President Donald Trump’s order to bomb Iran’s nuclear facilities presents a new test of the Constitution and the extent of presidential powers to conduct war despite a lack of congressional approval.

The President’s disastrous decision to bomb Iran without authorization is a grave violation of the Constitution and Congressional War Powers. He has impulsively risked launching a war that may ensnare us for generations. It is absolutely and clearly grounds for impeachment.

"I think President Trump was wrong. He went against the Constitution." Rep. Adam Smith (D-Wash.), the top Democrat on the House Armed Services Committee, joined Chris Jansing on MSNBC Reports to discuss the legality of President Trump’s move to launch military strikes on Iran.
