In an interview on 60 Minutes last month, the Republican Speaker of the House, Rep. Paul Ryan, was being asked about his opinions of Donald Trump. One of his answers included the following quote (emphasis is mine):
"We've talked about the Constitution, Article 1 of the Constitution, the separation of powers. He feels very strongly actually that under President Obama's watch, he's stripped a lot of power away from the Constitution, away from the legislative branch of government, and we want to reset the balance of power so that people and the constitution are rightfully restored."
Question: Has power been stripped from the Constitution (e.g. powers or responsibilities of the government's system of checks & balances) during President Obama term?
