Things like this are why the Democrats want so badly to damage Barr

The Obama White House kept tabs on a Freedom of Information Act (FOIA) request for information on former Secretary of State Hillary Clinton’s email accounts that the State Department improperly denied, according to newly released emails.

The emails, which were provided to Judicial Watch, show for the first time that the Obama White House was aware of the Clinton-related FOIA request, which the liberal watchdog group Citizens for Responsibility and Ethics in Washington (CREW) submitted to the State Department in December 2012.

The State Department denied the request in May 2013, claiming that no responsive records existed. That despite officials at the State Department, the White House and even President Obama himself knowing that Clinton used a personal email account for government business.
So they knew she'd been violating law, on this even if they didn't know about other things(chance of them not knowing?  Just about zero).

And this is just the start.  Pelosi and Schumer & Co. are going to get even worse in the near future.
