Lame comparisons with Al Capone fail to acknowledge that Trump wasn't asking anyone to do anything illegal.  Even Comey acknowledged  during his testimony the President's plenary power to decide who to investigate.  So how could talking about Flynn be "inappropriate"??  Furthermore,   "obstruction of justice" requires "corrupt intent", and a "hope" for a certain outcome falls far short of that element.

As for airily dismissing Comey's leak as not damaging to national security, say what?  Has  Lankford seen the info leaked to the private third party?  What if the latter revealed only a portion to the press, and reserved for himself "the good stuff", the part that actually damaged national security? Lankford's clearly speaking without the facts.

And... Comey was specifically asked by Sen. Grassley two weeks ago whether he had leaked anything to the press, or indirectly to a third party, and Comey said "No" to both. 

 There's yer lying under oath, right there!
