WASHINGTON – A former top aide to EPA Administrator Scott Pruitt is under investigation for claims she was a no-show employee – a charge she vehemently denies.

Samantha Dravis, who resigned recently as Associate Administrator of the EPA’s Office of Policy, faces a review by the Inspector General at the Environmental Protection Agency.

“After analyzing your request, we have decided to conduct the requested review,” Inspector General Arthur Elkins said Monday in a letter to Sen. Tom Carper (D-Del.).

Carper, the top Democrat on the Senate Committee on Environment and Public Works, requested the inquiry into Dravis’ attendance on March 28.

Dravis, 34, is the ex-girlfriend of former White House Staff Secretary Rob Porter. He left his job as a key aide to President Trump in February when domestic abuse allegations from his two ex-wives became public. Porter called the abuse allegations “outrageous” and “simply false.”

The three-month period of time that Carper alleges Dravis was an absentee employee is around the time she and Porter were living together.

“I have been informed that Ms. Samantha Dravis … did not attend work or perform her duties for much, if not all of the months of November 2017-January 2018,” according to the letter Carper wrote to the IG.

In a statement to The Post, Dravis called that allegation “completely false.”

“The accusation that I missed work from November 2017 – January 2018 is baseless and completely false. As Associate Administrator for Policy, I led the successful deregulation effort at EPA throughout the first year of the Trump Administration. I have never been absent from work for months at a time, nor have I neglected my duties during the time period in question. My calendar records, time sheets, email records will show this, and all of my EPA colleagues know that I have worked tirelessly and diligently during my entire tenure,” she said.

Sources close to Dravis say her resignation had nothing to do with Carper’s allegations and she didn’t even hear of his request for an investigation until after she had submitted her resignation.

The Post has learned that a former colleague of Dravis’s has been sharing ethical concerns about the Pruitt Administration with Congress.

Dravis said she left the EPA to explore new opportunities in the private sector.

The EPA did not respond to a request to review Dravis’s calendar, but agreed the charges are “completely baseless.”

“Samantha Dravis has been a senior leader at the EPA and has performed her duties faithfully for her entire tenure,” EPA spokesman Jahan Wilcox told The Post. “It is completely baseless and absurd to assert that someone with her responsibilities and office would have been away from her duties and responsibilities for months at a time as alleged.”
