Those are the words used in Article II Section 3 of the US Constitution. The president is also to "recommend to their Consideration such Measures as he shall judge necessary and expedient." Why does this not come up in Article I with all the other supreme powers of our Commander in Chief? Well, because only the military has one of those, and Article I is devoted to the most powerful branch of our government, the Congress.
The president is supposed to inform Congress on how things are going in his work of executing the laws they pass. We didn't hear much of that on Wednesday. President Obama did not mention his ban on prosecuting torture, his advisors' claims that he has the power to torture, his use of rendition, his removal from the Constitution of the right to habeas corpus, his list of Americans to be assassinated, his warrantless spying, his protection of Bush, Cheney, and gang from exposure or prosecution, his continuation of illegal wars, his use of unmanned drones to assassinate and slaughter, or his assertion of the power of aggressive war in a Nobel Peace Prize acceptance speech. All of that went without saying.
