Former Homeland Security official weighs in on Biden classified document probe

As more questions arise from the discoveries of government documents found in President Joe Biden's offices and home, elected officials and government watchdog groups are

expressing concerns about the security of important documents. The latest news comes months after it was revealed that former President Donald Trump had several boxes of

top-secret government documents at his Mar-a-Lago ranch last summer. John Cohen, an ABC News contributor and former acting undersecretary for intelligence and analysis at

the Department of Homeland Security, spoke with "Start Here" Monday about the probe and how government documents are handled. START HERE: John, I should point out you

were acting under President Biden, you resigned last spring when Biden’s full-time pick was about to be confirmed…but you know this space very well. How do documents like this

just keep popping up?
