A Democratic-led congressional committee voted on Tuesday to subpoena a former White House security clearance chief over whistle-blower allegations that the Trump administration inappropriately reversed career officials' decisions to deny security clearances to some of the president's advisers.

Elijah Cummings, chairman of the House of Representatives Oversight Committee, led the push to subpoena Carl Kline, who was White House personnel security chief for the first two years of Trump's presidency and now works for the Department of Defense.

The committee voted to approve the subpoena for Kline, with 22 Democrats voting in favor and 15 Republicans against.
