If you want to identify "corruption rewarding corruption" how about Eric Holder's justice department, where Holder described himself as Obama's "wing man" selectively using his prosecutorial power to punish a critic of Barack Obama.

The same way Obama used the IRS to audit, harass and intimidate his political enemies.

The same way Obama used illegal FISA warrants to spy on and frame the Trump administration with manufactured perjury and other means to frame Trump officials.
