WASHINGTON, DC, USA (AP) — A career official in the White House security office says dozens of people in President Donald Trump’s Administration were granted security clearances despite “disqualifying issues” in their backgrounds, such as concerns about foreign influence, drug use and criminal conduct.

Tricia Newbold, an 18-year government employee who oversees the issuance of clearances for some senior White House aides, said she compiled a list of at least 25 officials who were initially denied security clearances last year because of their backgrounds. But she says senior Trump aides overturned those decisions — moves that she said weren’t made “in the best interest of national security”.

Newbold’s allegations were detailed in a letter and memo released yesterday by Rep Elijah Cummings of Maryland, chairman of the House Oversight and Reform Committee. Cummings’ panel has been investigating security clearances issued to senior officials, including Trump’s son-in-law Jared Kushner, former National Security Adviser Michael Flynn, and former White House aide Rob Porter.

The documents don’t identify the officials on Newbold’s list but they note that two are “current senior White House officials”.

The release of the information comes about a month after The New York Times reported that Trump ordered officials to grant Kushner clearance despite the objections of national security officials, and after Newbold spoke out to NBC News and other news outlets about her concerns. It also sets the stage for another fight between the White House and the Democratic-controlled House. Cummings said he will move this week to authorise his first subpoena in the probe.

Cummings said the subpoena will be for the deposition of Carl Kline, who served as the White House personnel security director and who supervised Newbold. He has since left the White House for the Defense Department.

The White House did not immediately respond to a request for comment yesterday.

Rep Jim Jordan, the committee’s ranking Republican, said in a statement that Cummings’ probe is a “partisan attack” and an “excuse to go fishing” through personnel files. He also said that one person on Newbold’s list is a GSA custodian.

Newbold laid out her experience in the White House during a March 23 interview with bipartisan committee staff. Portions of that interview were in the memo released by Cummings.

According to the memo, Newbold’s list of overturned security clearance denials included “two current senior White House officials, as well as contractors and individuals throughout different components of the Executive Office of the President”.

“According to Ms Newbold, these individuals had a wide range of serious disqualifying issues involving foreign influence, conflicts of interest, concerning personal conduct, financial problems, drug use, and criminal conduct,” the memo said.

Newbold said she raised her concerns up the chain of command in the White House to no avail. Instead, she said, the White House retaliated, suspending her in January for 14 days without pay for not following a new policy requiring that documents be scanned as separate PDF files rather than one single PDF file.
