U.S. Sen. Lamar Alexander on Wednesday said his chief of staff in Washington, D.C., has been placed on leave as law enforcement agents search the man’s home to investigate child pornography allegations.

“I was just informed by the United States Senate legal counsel’s office that law enforcement agents are conducting a search of the personal residence of Ryan Loskarn, the chief of staff of my Washington, D.C., office, regarding allegations involving child pornography,” Alexander said in a Wednesday morning statement. “I am stunned, surprised, and disappointed by what I have learned. Based on this information, I immediately placed Mr. Loskarn on administrative leave without pay. The office is fully cooperating with the investigation.”

U.S. Postal Inspectors conducted the raid of Loskarn’s home, according to NBC News.

“The Postal Inspectors Service was involved in a law enforcement action in Southeast D.C.,” a spokesman for the agency told NBC News, declining further comment.

Loskarn is a longtime Alexander aide and was named the Tennessee Republican senator’s chief of staff in 2012, according to Politico. [Read more…]
