What US legal title do you wish me to cite, Title 10, 32, 50, etc because none give the Prez the authority you want (Thank God!)!
It’s very simple the President is head of the executive branch of the federal government. He only has legal authority over subordinate members of the executive branch of the federal government. The sheriff is in county government, a completely separate sovereign entity from the federal government. In most states the sheriff’s office is very independent of the state government. (Also the state governments are sovereign entities from the federal government! Could Obama order the arrest of a GOP governor say Texas’s Perry?) In common law & practice the sheriff is the top law enforcement official in the county, elected by the people for better or worse. Getting rid of one outside election defeat isn’t simple! In the Broward County case he’s done nothing illegal as near as I can tell. Breath-taking incompetence at one’s job is not necessarily against the law. Even if it was its not Trump’s job to fire him, its Florida as a whole and the Broward County voters. Trump could jump up & down all day and demand the sheriff be fired it would have no legal effect. If Trump actually took action he would be misusing his authority and that would be grounds for impeachment and likely criminal prosecution later. I assume you want to win this thing, be patient!
You seem to want Trump to be king, he’s not nor I am sure would he want to be. Leave those tyrant dreams to the Rats.
You still have not sited the law....
You are the one that said President Trump would be breaking the law.
Site the law YOU STATED he would be breaking.
