WASHINGTON, D.C. -- An employee of the Secret Service assigned to the White House has been arrested and charged with sending sexual content to a minor, according to court documents.

Lee Robert Moore, who the Department of Justice says is employed by the USSS Uniformed Division and currently assigned to the White House, has been charged with "attempted transfer of obscene material to a minor" in Delaware federal court, according to court documents.

According to the criminal complaint, he allegedly sent pictures of his "exposed erect penis" to someone he believed to be a 14-year-old girl via a social media app on a mobile device.

Court documents say Moore is 37 years old and lives in Church Hill, Maryland. The court documents, filed on Nov. 9, 2015, allege that Lee had a profile on a the social media application "Meet24" that described him as a 30-year-old male from Sarkey Corner, Maryland. According to documents he also used the "Kik" app to communicate.

According to documents, he reached out to undercover Delaware State Police Detectives who were posing as underage girls. He then sent photos of himself and sexually explicit messages to a person he believed was an 14-year-old. During an interview with authorities, he admitted to communicating with who he believed was a teen girl while on the job at the White House.

According to documents, he also admitted using "Meet24" to communicate with numerous other users who he believed to be minor, teenage girls.

In a statement a USSS spokesperson said, "The Secret Service takes allegations of potential criminal activity extremely seriously. This incident was reported to our Office of Professional Responsibility on Friday, November 6th. On that same date the employee's security clearance was suspended and the employee was placed on administrative leave. All Secret Service issued equipment was retrieved and the employee's access to all Secret Service facilities was terminated."

This incident is the most recent in a string of embarrassing incidents that have plagued the Secret Service.

In April, the Secret Service placed a high-ranking supervisor on administrative leave and suspended the supervisor's security clearance after what it called "allegations of misconduct and potential criminal activity."

Xavier Morales, a senior supervisor had been celebrating a promotion on the night he allegedly made unwanted sexual advances toward a female colleague, reported CBS News correspondent Bill Plante.

The woman told officials Morales grabbed her and tried to kiss her, but gave up after a struggle. When the incident was reported, his security clearance was suspended and he was placed on leave.

Morales had been promoted as part of a restructuring of the agency after several other incidents, including a 2012 prostitution scandal during a presidential trip to Colombia and a security breach in September 2014 that allowed a fence jumper to run all the way to the East Room of the White House.

In March, two senior agents drove into an active bomb investigation at an entrance to the White House compound. The agents were coming from a colleague's retirement party and officers on the scene reported that they seemed "extremely intoxicated."

Last month, in a "management alert" from Inspector General John Roth to Secret Service Director Joseph Clancy, federal auditors said they "observed two officers sleeping at their posts" on August 11, 2015.

One officer was assigned to the White House, and the other, reportedly to the Israeli embassy.

One of the two officers disciplined admitted to taking cold medicine prior to working.
