Well this is my theory on it. The Cabal is preparing to sacrifice Bush for 9/11. So they have Bush go out and support Trump's pick, praising the Senators who vote for Kavanaugh. This is an attempt to slide Bush in to look like a Trump ally. The 9/11 papers that were approved for release recently will show Bush involvement in 9/11 and only his involvement. This will be devastating to any Republicans that we're in office at that time, and they will likely go for treason charges against them. That's what I see the Democrats setting up. On the flip side of that I can see this being the "oops" moment Q referred to, they only asked for certain pages but the whole thing gets sent out instead. Oops.
Is it plausible that the Presidential Alert pinged the stealth sub. It could not be bypassed so I am speculating
