A group of Democratic lawmakers is calling for Jared Kushner's security clearance to be suspended after revelations that President Donald Trump's son-in-law omitted "dozens" of contacts with foreign officials, including Russians, on a questionnaire he was required to complete in order to be granted top-secret clearance.

In a letter to FBI Director James Comey on Thursday, Democratic Rep. Don Beyer of Virginia called the omissions of foreign contacts a "significant issue" for members of the president's transition team and administration.

Kushner, a senior White House adviser, has become the administration's point person for many matters of diplomacy and foreign policy. The New York Times reported last week that among the contacts Kushner left off his disclosure forms were a December meeting with Russian Ambassador Sergey Kislyak and the head of a Russian state-owned bank.

"Mr. Kushner's lack of candor about meetings with Russian officials appears to be part of a larger pattern of dissembling and deception on Russian contacts from the Trump team, and we believe the public deserves the truth about what connection, if any, exists between these incidents," Beyer said in a statement released alongside the letter, which was also signed by Reps. Ted Lieu of California, Jamie Raskin of Maryland, Jerry Nadler of New York and Peter Welch of Vermont.

The letter notes that knowingly falsifying information on the forms is a felony punishable by up to five years in prison.

"Given the severity of the allegations and still unanswered questions about this administration's recently uncovered covert dealings with Russian government and intelligence officials, we are requesting that Mr. Kushner's interim top-secret security clearance be suspended pending a review of Mr. Kushner's compliance with the laws and regulation governing security clearances," they wrote.

"The fact that Kushner is President Trump's son-in-law does not place him above the law," they added in the accompanying statement. "Anyone else would face severe discipline for failing to disclose meetings with foreign officials, a material omission which potentially amounts to a criminal offense."

Kushner's lawyer called the omissions an error that occurred when his form was prematurely submitted so he could receive interim clearance. It is not unusual for forms to be amended with additional information, and Kushner is expected to compile a more complete picture of his meetings to share with the FBI when he is formally interviewed.

"During the presidential campaign and transition period, I served as a point-of-contact for foreign officials trying to reach the president-elect," Kushner told the FBI after learning of the error, a statement from his lawyer said. "I had numerous contacts with foreign officials in this capacity. … I would be happy to provide additional information about these contacts."
