Ann Coulter brought that up in her recent townhall.com column. I didn't know about that.
Again, how can a marriage that spawned two children be annulled? Lots of Ketchup money donated to the church?
There is a misunderstanding of what Catholic annulment is. The Church recognizes that a legal marriage took place. They require a legal divorce before the annulment process is considered. Children are therefore not illegitimate. Catholic annulments rule on the sacramental nature of the marriage. Two different things.
Note: you can get a legal annulment if the divorce occurs within the first year. Again, that's a different matter from the Church.
