Are you commenting on president-elect Trump? I don't feel this is the case with him. But to answer the question, certainly not. Not only must our president adhere to and uphold the law, he will be involved in signing bills into laws. I would not trust anyone who wants to ignore the law but certainly not the president.
No, we cannot trust a president who wants to ignore laws. On inauguration day, the president takes an oath to uphold the U.S. constitution and the laws of our country. By ignoring laws, the president would be breaking the solemn oath he has taken. People who break oaths should not be trusted.
A president who wants to ignore the law is not a person who has earned our trust. The U.S. Constitution establishes the powers that the president does and does not have, and anyone who is willing to ignore this system of checks and balances for his own personal gain should not continue in the role of president.
Presidential powers are limited by the Constitution. If a President goes beyond those powers, then the either the Congress, through impeachment, or the Supreme Court, through a Judicial Opinion can curb that action. It is important for the stability of the Country that a President not allow a matter to get to the intervention of either of the two branches as that sort of thing will only erode the confidence that the populous has in the Government.
