Chaos45 second Veto on resolution cut off U.S. support to Saudi campaign in Yemen Article from The Hill (note another part: congressmen appealed to Trump's distaste for U.S. military entanglements in the Middle East to approve resolution) Also see article from Vox As expected Chaos45 vetoed it, but this is the part of his statement that caught my eye. Trump said in a memo to the Senate signaling his veto. The power is of the President, so is should say "weaken the Presidents constitutional authorities". Also, "The Constitution, of course, gives war declaration powers to Congress, not the president." So what power is Chaos45 talking about?
