(CBS News) Picking apart Republican vice presidential candidate Paul Ryan's budget, the Obama campaign has found a new issue on which to attack him: Education. His campaign released a new television advertisement Wednesday saying the Ryan plan would "cut education by 20 percent."

"This bill will help people stop drawing a welfare check and start drawing a paycheck," Mr. Clinton says in the video footage.
The ad then goes on to show footage of President Obama in 1998 saying, "I was not a supporter of the federal plan that was signed in 1996."
