When Congress overstepped its constitutional authority

Congressional Republicans are promising to go to battle with President Obama over his upcoming executive action on immigration. They claim he is overstepping his constitutional authority as president. We're hearing things like perhaps they'll sue him, or try to impeach him, or perhaps shut down the government in response.

What didn't capture as many headlines was the time President Obama said that Congress had overstepped their constitutional authority. What...you don't remember that happening?

When signing the National Defense Authorization Act in 2013, President Obama included statement that outlined the various ways provisions in that bill impeded his constitutional authority as Commander-in-Chief. That included things like limiting his ability to transfer Gitmo detainees to another country and disrupting his ability to implement provisions of the START Treaty with Russia on nuclear weapons.

The President didn't decide to sue Congress or shut down the government over this. He simply noted it and then went on doing his job to the best of his ability.

Just sayin'...
