Two Secret Service agents, assigned to protect Donald Trump III, President Trump’s 8-year-old grandson, face an internal investigation after it became learned that they took selfies with the boy while he was sleeping, a source with knowledge of the investigation has told Mother Jones.

The source made clear to Mother Jones that the agents are not under investigation for criminal behavior. The investigation instead focuses on whether the agents abandoned their post while charged with protecting the president’s grandson.

The incident reportedly took place last weekend when the agents were driving the boy from Westchester County, New York, where the Trump family has an estate, to Manhattan. Trump III was sleeping in the car when the agents began to take selfies with him.

The boy woke up and was “freaked out,” as the source described it. Upon return to Manhattan, he told his mother Vanessa Trump, who shared her concerns with his father, Donald Trump Jr.

Mother Jones said the issue was quickly escalated to top management of the Secret Service. The two agents were ordered to report to the Secret Service Office of Professional Responsibility in Washington, DC.

A Secret Service spokesman confirmed to Mother Jones that an investigation was underway.

“The US Secret Service is aware of a matter involving two of our agents and one of our protectees,” the spokesman said in a statement. “Our Office of Professional Responsibility will always thoroughly review a matter to determine the facts and to ensure proper, long-standing protocols and procedures are followed. The Secret Service would caution individuals to not jump to conclusions that may grossly mischaracterize the matter.”

Mother Jones notes that this news comes at a time when the Secret Service is doing “damage control” after an intruder last Friday night was able to penetrate the outer perimeter of the White House grounds and get close to the entrance of the north portico of the White House. The intruder was a 26-year-old San Jose State University graduate from Milpitas who was caught carrying two cans of Mace and a letter to the president about “Russian hackers,” according to a sworn affidavit from the Secret Service cited by the Washington Post.

Trump, who was in the residence at the time, praised the Secret Service for doing a “fantastic job” arresting Jonathan Tuan-Anh Tran, whom the president called a “troubled person.”

Sources told Mother Jones that President Trump has had a good relationship with Secret Service agents, and the incident with his grandson is not symptomatic of issues that either he or his family have with their protective details.
