Q
Maybe you misunderstand the term 'sleeper' used in Q context.
Q said (and by extension, Trump said), TRUST WRAY.
When it was proven that he could no longer TRUST WRAY, Q adised that Wray was a SLEEPER.
Which means that Wray was derp all along, pretending not to be. And that went for many other SLEEPERS in Trump's orbit.
But in general, the term applies to derps not identified as derps yet. Like Pence.
So, yea. Trump trusted Wray. Until he didn't. That's how life goes. I used to trust my ex-wife, for example.
