Criticism Of President Trump

I wonder if the same "Christians" that are criticizing President Trump spend as much time praying for him as they do criticizing him. I have read in 1 Timothy 2:1-3 how that praying for those in authority is to be done by Christians and that this is good and acceptable in the sight of God our Savior. I don't remember reading anywhere where we are to be criticizing the leaders of our countries in this world. Numbers 11:1 says "And when the people complained, it displeased the LORD: and the LORD hear it; and his anger was kindled; and the fire of the LORD burnt among them, and consumed them that were in the uttermost parts of the camp." The next verse says that when Moses PRAYED unto the LORD, the fire was quenched. Maybe there is some wisdom in this for us to apply to Christians criticizing President Trump. Since Psalms 75:6-7 and Daniel 4:17 both speak of how it is God that raises people up to positions of authority and power, maybe Christians should be more careful with their criticisms of President Trump.
