The answer based on an anonymous Op-Ed in the New York Times is YES!
Democrats should not be clapping their hands with delight over this situation. The same insider behavior could have occurred during the Obama administration.
The single person that all Americans elect to lead the country is the president. Members of the House of Representatives and Senate are elected by the district or the state. We rely on the president to lead the entire nation regardless of political party or other affiliations.
There is nothing in the Constitution that gives anyone authority to countermand the president’s decisions except laws passed by the congress or rulings by the Supreme Court.
When other people attempt to undermine or delay the president’s decisions they are interfering with the process of government that has been the basis of the American democracy since its inception.
While I view Donald Trump as a bad leader who could cause a war or an economic catastrophe he is the person that our system of elections has chosen to be president. Unfortunately his faults are many. Trump has been a supporter of groups that sew hate and he has made many nations that were considered allies into enemies.
Despite his obvious failings, I am not comfortable with an inner circle of people in the White House who are attempting to control the decision making process in the White House. They may say their actions are to protect our country but they are unanswerable to the American people.
We do have three ways of removing president. 1) Not re-elect him for a second term, 2) Action taken by the Vice President and “principal officers of the executive departments” to remove the president from power, 3) Impeachment. All of those choices are better than undermining our system of governing.

I would like to add that this president was elected by a minority in our country and is possibly the most corrupt man to ever be president. Imagine it the people in Germany under Hitler had worked harder to resist , then maybe Hitler would not have gained power.
I think to say that President Trump is one of the most corrupt, is a stretch. We have to remember that virtually every President has has scandals. And the blame cannot be laid solely at Trump’s feet. We also have to remember that we, as Americans, always talk about change and reform, when all we really mean is that we are tired of one party or the other. We are the most deluded people of the face of the earth! If we were really interested about change and our Constitutional rights, politicians like John McCain wouldn’t die in office; they would die in retirement in some obscure town far, far away. Chuck Schumer and Nancy Pelosi should should have been given their walking papers a long time ago.
And comparing Donald Trump to Adolf Hitler is a real slap in the face to the Jews and what they experienced during the Holocaust. Correct me if I’m wrong, but I don’t see Donal Trump putting people in concentration camps and killing them by the dozens in gas chambers.
