We go through background checks for mostly any job right?

Should not the president of the U.S.A. do the same? The activities, schools, religious groups or cults, they've pledged allegiance to. Drug use, family background check, including brothers and sisters. It has to be important that the president has had no contacts, with terrorist, or bigots, people known to be or have been enemies of our country, even if it's through ociation. There is one person who does not fit the bill, to be this countrys president.
