His duties and powers are explicitly spelled out in the Constitution. None of these includes spending government funds to travel across the country in order to give a motivational speech/eulogy. Is it his job to be the head of the executive branch of government or a celebrity speaker?
Get your Constitution right. Funds for executive travel are appropriated by Congress. He is allowed to make travel arrangements as he pleases with those funds. If you want him to sit in an office all day and sign papers, you are bitching about the wrong branch.
I have some respect for the strict Constructionist position. I don't want people running roughshod over the Constitution. However, it always baffles me when people go as far as you do. I have to simply shake my head and wonder how you've managed to become so obtuse.
When the Constitution was written, the idea of "traveling across the country" didn't exist. We didn't have much of a country to travel across, let alone the ability to do so in a matter of hours. His ability to function as head of the executive branch was in no way limited, as he was flying on an Aircraft so sophisticated that if the Founding Fathers had seen it they would have been utterly terrified.
We have a grand total of two nationally elected representatives. The President and Vice President. When someone directs violent action against the Constitution, it is their sworn duty to respond. There is plenty of evidence that this was an intentional attack on a democratically elected federal representative. That's an attack on the foundation of our federal legislative body, which means it's an attack on the Constitution. Prior to doing so he dispatched appropriate officials to begin a federal investigation.
However, I doubt any of that rings true with you.....so I'll bring something else up.
This is the topic and time you choose to angst about Executive Overreach on a forum? The President flying to give a speech after a Congresswoman was shot while meeting with her constituents? When we have undeclared wars being waged, people being locked up without being charged, and god knows what else. Yet you choose to attack him for flying to AZ in order to offer what condolences he could? How petty can you get? You claim to have no political affiliation, but it's fairly obvious based on your posts that you do. "Troll."
