Marco Rubio branded 'pathetically weak' as Twitter suggests ways to reward teenagers for their bravery

"Parents, what would you do if your child lectured and ridiculed a U.S. Senator on national television?"

At a town hall meeting held by CNN in Sunrise, Florida, on Wednesday night, thousands of angry students, teachers and parents booed Republican Senator Marco Rubio when he indicated that he would not support an assault-weapons ban and applauded Democrat Representative Bill Nelson when he pushed Mr Rubio to work on a bill that they both could support.
