Secret Service Sex Scandal! Michelle Obama's Personal Agent Secretly Disciplined Over X-Rated Texts — Does Barack Know?

Incriminating text messages and a lewd "selfie" that the agent sent to the woman were also uncovered during the probe.

The discovery is bound to send shock waves through the already scandal-scarred federal agency, tasked with ensuring the safety of the President and his family, and whose tarnished motto remains, "Worthy of Trust and Confidence."

As RadarOnline.com reported, 13 agents were blasted for their involvement in hiring prostitutes on a presidential trip to Colombia in 2012.

And just last year, a screwball jumped the White House fence and evaded agents, making it all the way into the building. The scandal resulted in the resignation of director Julia Pierson, but even her successor, Joe Clancy, admitted to lawmakers in March that boozy antics are still ingrained in the elite club.

The latest alarming events unfolded on May 20. The ENQUIRER did not name the agent and the female staffer at the center of the scandal, although multiple sources have confirmed their involvement.

A close source with specific knowledge of the agent's disturbing actions said he was posted outside an event Michelle attended that was co-hosted by former Sen. Elizabeth Dole for veteran caregivers in Washington, D.C.

"While on his protection assignment, the randy agent chatted up a woman he had the hots for!" the D.C. mole claimed.

According to a high-ranking government source, fortunately there were no security breaches at the event.

But later that night, the agent coyly texted the target of his lust.

He wrote: "Hi ... it's ---- (Secret Service). Wanted to say it was a pleasure meeting you today. You helped make a routine assignment interesting."

That seemingly innocent text was followed by overtly aggressive "sexts" concerning the staffer's weekend plans.

When she replied, "You and I didn't have plans," he shamelessly answered: "We need to change that. I want to taste your p---y."

The horndog agent then sent a snapshot of himself wearing the black slacks and white shirt typically worn by Secret Service members, with a bullet clip on his hip.

He later sent the stunned staffer an XXX-rated photo of himself wearing the same clothes with a tie — and flashing his exposed penis!

In another act of betrayal, The ENQUIRER learned the agent recently married.

Faced with the allegations, the Secret Service acted swiftly: It launched an official investigation and stood down the love rat agent, placing him on administrative leave.
