What should be done if the President is mentally ill?

Where were you Sandy over the last eight years as a deceitful Marxist did everything in his power to unravel our country, our unity and our financial strength? You desperately need to broaden your library and stop relying on the Soros funded media... I suggest The Drudge Report each morning with your coffee...

Not sure what you are getting at but we just came out of eight years of an immature and unstable president whose Vice President was senile and was surrounded by lunatics like fiction writer Ben Rhoades who ran our national security apparatus, Susan Rice who would openly lie to protect power and Marie Harf as spokesperson for all of it. Supplemented by leadership who would spy on the people and agencies who would bully the political opposition because our president's leadership was too weak to inspire confidence from the nation and the world. In the end, the only thing that removes a weak leader from power is an election when a VP like Bidenis too mentally feeble to take control.

I was not a fan of Obama, I believed he was unqualified for the office. But he was my Commander and Chief. I followed the order to deploy for the fourth time, and I followed the orders he gave without ever questioning his authority.
As a Commissioned Officer, I do not take an oath to the President, but to the United States Constitution.
I am dishearten to see so many Enlisted and Officers, both currently and previously serving in our military defaming a sitting President.
You, you are the domestic enemy our founding fathers warned us about. And what I swore an oath to defend against.
I, [name], do solemnly swear (or affirm) that I will support and defend the Constitution of the United States against all enemies, foreign and domestic; that I will bear true faith and allegiance to the same; that I take this obligation freely, without any mental reservation or purpose of evasion; and that I will well and faithfully discharge the duties of the office on which I am about to enter. So help me God.

Yes, Obama was a narcissistic unqualified joke. He will go down in history as being the greatest fraud ever perpetrated on the American people.
Now President Trump is our Commander and Chief, and deserves the respect that goes with the office.

I Don't trust any politician. Every person running for office says the same thing. Doesn't matter what party.

People in the military today are too young to remember the transition from Jimmy Carter to Ronald Reagan. President Carter appeased the Soviet Union, allowing it to grow stronger. He failed to support the Shah of Iran, creating the environment for contemporary Islamic Jihadism. His 'environmental friendly' policies severely damaged US industry and the economy. When President Reagan was elected the Democrat Party and the communist propagandists in the media said he would start WW3. Just the opposite happened. America gained respect, the Soviet Union was broken up, the jihadists were pushed back, and the economy improved. Clearly, 1LT Annala and those that agree with her are victims of the communist propaganda that is taught in our schools & perpetuated in the media. Unfortunately, the Democrat party has also embraced communism (socialism, etc), giving it legitimacy, even though historically it has always failed as a system of government. 1LT Annala should spend some time studying history so she can properly respond to the seditious propagandists who tirelessly work to destroy America, and her system of government which has proven to be the best that the world has ever known.

First of all, the question is not really valid as it is based upon an assumption, not a proven fact. I would suggest the mentally ill ones who are rioting in the streets for no logical reason, rejecting nominees that are well qualified simply because of who nominated them or marching about in giant vaginas. None of that is what a reasonable person would consider rational behavior.

But let us suppose for a moment, that the president IS indeed mentally ill. First, we have had as bad or worse and survived. But suppose action was needed, there is no need to assess the mechanism, the mechanism is in place, clearly outlined in Article I sections 2 and 3, Article II sections 2 and 4. Charges must be set forth in the House, and tried in the Senate, action is limited to censure or removal from office. Any action outside of those parameters would be a clear violation of the Constitution. Pretty simple and straight forward really.

How many more anti-trump questions are you going to make? Whatever feelings you have for trump, I can guarantee I had 1000 time more negative feelings for Obama. I laugh at the fact that you are actively undermining your boss, but, I would be willing to bet, you would be the first to jump in the ass if one of your subordinates did this to you.
You are an officer in the US military, start acting like it.

Sp4 Byron Skinner Not so quick. First off I doubt if you would find any compeniant Healthcare Professionals who would make such a deliberation based on what we know. To prove that a President is Mentally incapable of performing his job is a long process both medical and legal. I would imagine that it would go all the way to the supreme court. The 25th. Constitutional Amendment Section 4 is rather ambitious how a President's ability to serve can be determined. The 25 Amendment was written on the assumption of injury or illness not mental ability to function. There is only one Doctor in the current cabinet, Ben Carlson, a Neurosurgeon. The Presidents behavior has not really noticeably changed since the election. Sorry guys you got what you voted for.

A leader who puts America first, a leader who wants to stop illegal immigration? And you reference NYT? All that shows your true colors.
