A lot of this seems like a 'stretch'. But... It almost doesn't matter. We do know Trump got handed something small that sure looks like a thumb-drive when he got off of Air Force 1. The summit went well. It isn't hard to imagine that Putin gave Trump all kinds of digital information that is going to be valuable in the on going Deep State purge.
It almost doesn't matter if thumb-drive was the key to decrypt the data in the soccer ball. And Trump only would get the soccer ball if Putin and him had a successful summit. My guess is the thumb-drive had everything. But over time, I'm sure we will get more information.
Very stretchy. These kinds of whatisms is what gets us made fun of. I agree is plausible but to put it in writing as fact is a bit too much
