On CNN's "State of the Union" on Sunday, Sanders agreed.
There are young people who ... worked very hard to get a good education. They are living in their parents' basements and that's the point there.
Republicans attempted to paint Clinton's comments in a negative light, but Sanders argued they only illustrated his point.
Republican national committee spokesman Sean Spicer said Sanders supporters should "get out of your parents baement [sic] and listen to what Hillary Clinton thinks of you," according to The Guardian.
An email from the Trump campaign said voters "can't let Crooked Hillary get away with attacking the great citizens of our country," CNBC reported.
Trump himself attacked Clinton for the comments in a tweet.
