It is HIS OWN DAUGHTER’S WEDDING! I certainly understand the problem. The planning has been going on for months, if not over a year! It is a terrible decision.
It is also the Kavanaugh vote, and the planning has been going on for months. I say it is more important than a wedding. The wedding can go on without him for one. They could also postpone the vows and just have it at a Justice of the Peace if they want him there.
If this really is an issue, he and possibly his daughter sound incredibly selfish. I can’t even imagine going there and having a good time knowing that you were holding up the country on this pivotal moment.
