Also it's important to look at what Schiff really said. He's clearly playing word games. Nothing in his quote denies a spy actually being in the campaign, just that nothing they heard during the meeting changed their view, which is obvious because the DOJ refused to show them the documents. Notice how he said heard? That proves the DOJ refused the documents and didn't show them anything.
Problem for Schiff is, Clapper, Brennan and Comey have all three already admitted it.
“Nothing we heard today has changed our view that there is no evidence to support any allegation that the FBI or any intelligence agency placed a ‘spy’ in the Trump Campaign, or otherwise failed to follow appropriate procedures and protocols"
