Really? Then Why didn't you say something when Obama did it?
"The Iran nuclear deal was so bad that Obama didn’t bother informing Congress about the details, let alone ask them to do their constitutional duty of ratification? Well, when Congress wanted answers, the White House
refused to let the architect of the deal, Ben Rhodes, testify. Rhodes was the failed novelist who became the architect of the Iran deal. They cited “separation of powers” and all that. White House counsel Neil Eggleston said at the time, “The appearance of a senior presidential adviser before Congress threatens the independence and autonomy of the president, as well as his ability to receive candid advice and counsel in the discharge of his constitutional duties.”
Just for your enjoyment here's another,
If not allowing administration officials to testify or fighting subpoenas in the courts is obstruction of justice and therefore an impeachable offense, then Barack Obama should have been impeached very early in his presidency for just that. When the Obama Justice Department decided to dismiss voter intimidation charges against the New Black Panther Party after the government had effectively already won the case, it raised many questions about the motivations behind that decision. The Obama administration
vigorously fought subpoenas and instructed officials not to testify.
