Additionally, the spokesperson said the actions taken by the Federal Protective Service (FPS) were not related to the ongoing internal inquiry.

The mission center Sulc runs falls under DHS’s Office of Intelligence and Analysis. Sulc is under investigation for allegedly violating security protocols by taking in a personal electronic device into the secured office, which is prohibited.

Sulc has neither been arrested nor charged.

A source familiar with the investigation told Fox News Digital that the Office of the Chief Security Officer searched Sulc’s office at 4:15 p.m. on Monday, covered his office with tape and placed evidence seals on the door and keyhole to his office.

Rolling Stone reported the tape used was crime tape, however a source familiar with the search told Fox News Digital it was only "tape."
