A quick google search with the term “General Flynn’s Security Clearance” brought up this and other numerous articles.

I was asking for evidence on what Spicer said in those two sentences. Not a general article about the Flynn case that doesn’t appear to include any related evidence that backs up those two Spicer statements. I’ve giving up trying to find it, all I can find is evidence disproving it. Like I said… never mind.
