Not if he is not invited, or disinvited.
This is a chance for Trump to make peace but not by forcing himself on them. Feelers must be sent. An invitation must be given.
I agree with you. The power of the current & present POTUS, Trump needs to be present. IMHO...nether Jimmy Carter, Bill Clinton or Barack Hussein Obama bring the honor, dignity, and respect that this funeral demands. George H. W. Bush served his country, every day he took and inhaled, God’s given breath of life!!!
