I do solemnly swear (or affirm) that I will faithfully execute the Office of President of the United States, and will to the best of my Ability, preserve, protect and defend the Constitution of the United States
That is the oath the President takes when assuming office. "protect and the Constitution of the United States" means defending the government based on the Constitution. The government was under attack, and Trump did nothing.
Trump could have called out the National Guard, or he could have started with a simple tweet. These were his supporters attacking the Capitol, a tweet telling them to leave would have taken a lot of steam out of the attack. Trump loves tweeting and never holds back when he disapproves of something. Trump did nothing.
I don't care how many words you use in an attempt to rationalize his inaction, there is no getting around the fact that Trump is guilty of dereliction of duty. He was a threat to the nation and will be a renewed threat if he is allowed to return to office.
People who put Trump before country are not patriot, they are cult members.
