From thepostmillennial.com , MSNBC host Chris Hayes asks on Twitter if the Hunter Buyden laptop story was ever proved to be true?

HOW DO YOU NOT KNOW THIS?

From the story:

Noah Blum made a similar point, noting that “If only [Hayes] were a member of a profession that’s tasked with figuring shit like this out instead of just musing about it on social media.”

Exactly.
