Story highlights Jared Kushner has made multiple updates to his security clearance questionnaire

Democrats have called on the White House to revoke Kushner's security clearance

(CNN) The head of a government bureau responsible for clearing background checks told lawmakers Wednesday he has "never seen that level of mistakes" when asked about numerous omissions in Jared Kushner's security clearance application.

Charles Phalen, the director of the National Background Investigations Bureau, a newly created division within the Office of Personnel Management, made the comment in response to a question during a House subcommittee oversight hearing.

Democrats have called on the White House to revoke security clearances granted to Kushner, President Donald Trump's son-in-law and senior adviser, and Ivanka Trump over reports of their use of personal email accounts and Kushner's multiple updates to his security clearance questionnaire, known as SF-86, for failing initially to include meeting with foreign officials.

Democrat Raja Krishnamoorthi of Illinois asked Phalen, "can you recall if there has ever been an applicant having to submit four addenda detailing over 100 errors and omissions being able to maintain their security clearance once those errors and omission have been identified?"

Phalen said he has not seen "the breadth" of all applications "but I have never seen that level of mistakes."
