Wouldn't it be better to pray that the President learns to always follow and obey God in everything? Wouldn't it be better to ask God to bless and care for all of the children and other people who are here with such difficulties? People who try to tell God what He should do may find themselves in trouble. God knows what is needed. Sometimes we think we do and are wrong. Remember these verses:
Jas 5:16 Confess your faults one to another, and pray one for another, that ye may be healed. The effectual fervent prayer of a righteous man availeth much.
Jas 4:3 Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts.
