(CNN) A top official at the Department of Health and Human Services has been placed on administrative leave after a CNN KFile inquiry while the agency investigates social media postings in which he pushed unfounded smears on social media.

Jon Cordova serves as the principal deputy assistant secretary for administration at HHS. A KFile review of Cordova's social media accounts found that he pushed stories filled with baseless claims and conspiracy theories, including stories that claimed Gold Star father Khizr Khan is a "Muslim Brotherhood agent" and made baseless claims about Sen. Ted Cruz's personal life.

"Mr. Cordova is currently on administrative leave while we look into this issue further," a HHS spokesperson said in a statement.

Cordova did not respond to a request for comment.

Cordova joined HHS in February of 2017, initially as part of the Office of the White House Liaison. In his current role, Cordova oversees day-to-day operations for the Office of Human Relations, Office of the Chief Information Officer, Office of Security and Strategic Information, Equal Employment Opportunity Compliance and Operations Office and the Program Support Center, according to his biography posted on the HHS website.
