A special aide to President Obama who discovered a cover-up at the highest levels of government—her Capitol Police boyfriend’s affair—is currently behind bars after allegedly taking revenge on him with his own service weapon.

Prosecutors say Barvetta Singletary, who also serves as a (dangerous) House Legislative Affairs liaison, laid her trap carefully, luring the adulterous victim to her home with the promise of sex. Then, when he was apparently incapacitated in post-coital bliss, she pounced, confronting him about the other woman.

But confess he would not, and things soon escalated—via NBC:

Investigators say Singletary asked her boyfriend to step outside, and they both went to his car. Once inside the car, police say Singletary asked to see her boyfriend’s cellphones. When he refused, Singletary reached into his bag and retrieved two cell phones and the victim’s .40 caliber Glock 23 service weapon, charging documents state.

Singletary ran back into her home and the victim followed, pleading with her to return his weapon.

That’s when she allegedly—and somewhat generously, for a scorned woman brandishing a stolen gun—offered not to shoot the boyfriend if he would give her access to his texts.

Singletary then pulled the gun out of its holster, pointed it at the victim and said, “You taught me how to use this. Don’t think I won’t use it,” the arrest warrant said.

When the victim again refused to give her the passwords, Singletary said, “Your phone is more important than me holding the gun on you.”

But his texts were apparently more important than the arguably crazed woman pointing a gun at him—he refused to unlock the phone. And unlike the two-timing bastard, Singletary kept her word: cops say she fired off a round in his general direction. The victim ran off into the night and in a somewhat bone-chilling detail, a neighbor says he watched Singletary wipe her fingerprints off the gun with a towel before police arrived.

Singletary, it may surprise you to learn, no longer has access to the White House. Technically.
