I've never understood the Hillary email "invetigation" obsession, except to the extent it reflected poor judgment was during the campaign, good GOP grist for the mill.  Same with a drop in by one famous politician to another.  They would be relevant if Sessions' DOJ were investigating them.  But,. . . well. . . are there investigations into any of them?

I believe Trump expressly stated to lester Holt that his decision to fire Comey involved Comey's pursuit of the Russia investigation.  Stop watching Fox, and you'll probably see the snippet where he expressly said that.

What are the legitimate questions as to the emails and Lynch?  

Why aren't the DOJ and Congress investigating those things?
