NEW: Sources tell me DHS Secretary Mayorkas is stonewalling the release of this DHS IG report, which would include any security failures or perhaps involvement by the Secret Service on January 6.For 2 years, the Biden White House, Democrats in Congress, and the media have attacked DHS IG Joseph Cuffari, who discovered that all of the texts belonging to roughly two dozen Secret Service officials including the head of USSS related to Jan 6 had been deleted at the end of January 2021--under the Biden regime.Cuffari sought a criminal investigation into the purge of the messages--which occurred AFTER Democrats notified each federal agency to preserve all records and documents for Jan 6.Instead, the J6 Committee and Biden White House started to smear Cuffari, claiming he failed to notify Congress about the missing texts--which is not true.Cuffari today announced an inquiry into the Secret Service for the attempted assassination of Donald Trump.
