He is not wasting his time. He is making a point and more people will be aware of what she said and how she won't apologize.
I meant he's wasting his time if he really expects her to apologize. It's not going to happen. However, you could have criticized me for saying Hilly would slither under her rock for awhile. In an unusual move for a clinton taking heat, I forgot she has run her mouth once again since Monday, concerning actions on Iran. Nothing but hot gas, but she did bloviate. She must be running for something.
