Fourteen Republican House members led by Rep. Marjorie Taylor Greene of Georgia demanded Washington D.C. Mayor Muriel Bowser terminate Deputy Warden Kathleen Landerkin of the D.C. Correctional Treatment Facility. Landerkin is overseeing the pre-trial detention of Jan. 6 Capitol riot defendants.

In the letter sent Thursday, Greene railed the warden for running a “two-tier justice system” based on a recent congressional visit from the Georgia lawmaker with Texas Rep. Louis Gohmert, who also endorsed Landerkin’s termination.

“January 6 defendants were treated categorically different from the remainder of the prison population,” they wrote, referencing testimony from the accused that claimed “months of solitary confinement, verbal abuse (e.g., called ‘white supremacists’), harassment, beatings from guards, denial of basic medical care, religious services, communion, nutritious diet, and access to attorneys.”

While most of these inmates have no prior history and have yet to be convicted of any crime,” lawmakers added, “Landerkin is allowing them to be treated as subhuman.” Greene published her findings from the November visit in a 28-page eyewitness report titled, “Unusually Cruel” on Dec. 7.
