The Trump-Clark DOJ coup attempt.. will anyone pay?

AG Bill Barr resigned on 12/23 leaving AG Jefferey Rosen to instantly get pummeled by Trump to overturn the electioin bust resisted. Rosen was being pressured by a junior DOJ official who had been sympathetic to Trump and 
even drafted a letter designed to be sent to the GA legislature to cast doubt over the election in an effort to overturn the election results in favor of Trump. How did Trump find a willing DOJ official to help pull this off? Whatever happened to Jeffrey Clark and will anything become of this Trump-Clark coup attempt that a DOJ watchdog group/ Congressional investigators are looking into?
