Attorney General Bill Barr is testifying before the Senate Judiciary Committee today, and during his opening statement, committee chair Lindsey Graham let Democrats know he plans to follow the trail of investigatory crumbs all the way back to the time when Obama was in office and James Comey was still the head of the FBI:

Sen. Graham, presiding over the Barr hearing, starts by reviewing the "no collusion" finding of the Mueller report – now he's going through the Strzok/Page texts and their handling of the Clinton email server investigation. — Anthony Zurcher (@awzurcher) May 1, 2019

"This committee is going to look long and hard at how all this started," Graham says regarding the initiation of the Russia counter-intelligence probe that eventually became the Mueller investigation. — Anthony Zurcher (@awzurcher) May 1, 2019

GRAHAM says the committee will investigate political bias in the DOJ during the 2016 election: "this committee is going to look long and hard at how this all started.” — Alana Abramson (@aabramson) May 1, 2019

Graham’s pledge to help Barr (who said something similar during previous congressional testimony) get to the bottom of how the “collusion” ball got rolling might make more than a few people nervous:

We're going to look at the FISA warrant process." https://t.co/U0hFpvmTbO pic.twitter.com/8WSUsHpJXt — ABC News (@ABC) May 1, 2019

Graham’s pledge to go back and find out how and why this all started in 2015/2016 isn’t sitting well with former Obama adviser Dan Pfeiffer:

I’m getting the sense that Lindsey Graham is not trying to get to the truth about Trump obstructing justice. — Dan Pfeiffer (@danpfeiffer) May 1, 2019

We don’t doubt that any suggestions to scrutinize the actions of the Obama admin, Comey, Strzok, Page et al be won’t sit well with Democrats.
