KANSAS CITY, Kan. (AP) — A federal judge in Kansas has ordered courthouse surveillance video preserved in a case involving a prosecutor’s visit to the judge’s chambers.

U.S. District Judge Julie Robinson’s order Wednesday directs authorities to produce all video from Aug. 25 to early Aug. 26 showing Assistant U.S. Attorney Erin Tomasic and a deputy marshal on the floor where Robinson’s office is.

The Kansas City Star reports (http://j.mp/2cMaVx4 ) the allegation that Tomasic entered the judge’s chambers without authority was made public during a recent hearing involving an investigation into recordings of attorney-client meetings at a private prison.

The U.S. attorney’s office says Tomasic wanted to deliver materials Robinson requested and had the marshal open a door to a hallway leading to the chambers, where she intended to slide the documents under the door.
