GOP House Intelligence chair says he's 'amazed' by how Biden, Pence and Trump handled documents

House Intelligence Committee Chairman Mike Turner says he and other members of Congress who deal with sensitive information are "amazed" by how President Joe Biden, former President Donald Trump and former Vice President Mike Pence handled classified information. 

"All of them keep finding documents that are classified," Turner said Sunday on CNN's "State of the Union."

Turner said he and other lawmakers are "all just stumped" and "don't understand how this could be happening" after all three leaders were found with materials marked as classified.

"We're just amazed as people keep finding them stuffed in the strangest places," he said. "We don't understand how all three could have been so lackadaisical about this."
