The third woman to accuse Supreme Court nominee Brett Kavanaugh of sexual misconduct as a teen is a Washington, DC, resident who has had a career working for the federal government.

In a sworn declaration released Wednesday, accuser Julie Swetnick, 55, notes that she holds “active clearances” for her work with the US Department of Treasury, US Mint and Internal Revenue Service.

She said she also previously had security clearances with the US Department of State, Department of Justice, Department of Homeland Security and Customs and Border Protection.

An active security clearance means Swetnick has been subjected to a stringent background investigation that deemed her qualified to have access to “classified national security information … so long as the person has a need to know the information,” according to the State Department website.

At the State Department, Swetnick was employed as a senior production web master from 2002 to 2005 and held the same job with the DOJ from 2006 to 2009, according to her online resume obtained by Heavy.com.

With Homeland Security and CBP, she worked as a senior web production manager in 2012, she said.

Swetnick noted she is “one of the first 100 women in the world to achieve a Microsoft Certified Systems Engineering Certification.”

The government worker claims that between 1981 and 1983, she witnessed Kavanaugh — a US Court of Appeals judge for the DC Circuit and President Trump’s Supreme Court nominee — and his pal Mark Judge “spike” the “punch” at high school parties and then line up outside a room in the house along with other then-teenage boys “waiting to rape a drunken girl inside.”

Swetnick alleges she was among the gang-rape victims at these parties, but doesn’t directly accuse Kavanaugh or Judge of raping her.

“In approximately 1982, I became the victim of one of these ‘gang’ or ‘train’ rapes where Mark Judge and Brett Kavanaugh were present,” she said in the declaration. “During the incident, I was incapacitated without my consent and unable to fight off the boys raping me.”

She said she told at least two other people about her alleged rape and said she believed she was drugged with Quaaludes.

Swetnick joins Dr. Christine Blasey Ford and Deborah Ramirez in accusing Kavanaugh of sexual misconduct.

Ford claims Kavanaugh tried to rape her during a high school party in the summer of 1982, and Ramirez alleges he shoved his penis in her face during a dorm room party at Yale during the 1983-84 school year.
