Why investigate? - Barr so corrupt, he didn't need to be told to intervene for Stone - 2020-02-12
The framing for most of the stories asks whether Trump pressured Barr to intervene on Roger Stone's behalf, but that's the wrong question because the answer is irrelevant.
Since taking the US Attorney General job, Barr has demonstrated a remarkable acuity to feeling out Trump's personal interests, probably more so than Trump himself. If Chuck Schumer's investigation is premised on who told what when, it's going to be a time-wasting snipe hunt.
No phone call between the two was necessary for Barr to know that Roger Stone was found guilty by a jury of committing a crime *on behalf of* then-candidate Trump. Stone did not cooperate. Barr, a smart lawyer, fully grasps the implications of the foregoing, that being that Roger Stone holds Trump's potential criminal liability in his hands. Stone isn't merely Trump's old scumbag-for-hire friend, he's a potential witness against Trump.
