Lots and lots of things are being written about this story, but what I like about Jon Sopel’s piece from BBC is that it’s short and brings a clarity of understanding to the timeline of what we know transpired. I highly recommend reading it in its entirety, slowly. Don’t skim it. If you comprehend it fully then it’s the only thing you need to read about the Flynn story to know way more than most people in the country at this point.
One lesson learned is this: when something bad occurs and few people know about it yet, and you’re trying to decide how to respond and you’ve come up with a plan, think about how that plan will be perceived if many people know about it. When Pence learned of the true nature of Flynn’s calls, he chose to do nothing. When the nation learned of the nature of Flynn’s calls, Donald Trump asked Flynn to resign. There’s a time and a place for your actions to vary depending on who knows what, but it involves risk. Because of Pence’s choice, there’s an air of fiasco to the administration surrounding Flynn that otherwise might not exist.
Of course, if there’s an investigation - there needs to be one, unquestionably, at this point - and if this investigation finds that the Russian ties go deeper, than my sympathy level for Pence in his predicament goes way down. The jury’s still out on that though.
