House Speaker Paul Ryan said Monday that Hillary Clinton should lose her security clearance after FBI documents revealed that a senior State Department official pressured the FBI not to reveal that she had classified information on her server.

"This is why our aggressive oversight work in the House is so important, and it will continue," Ryan said in a Monday statement.

Newly-released FBI notes show that Patrick Kennedy, State Department undersecretary for management, asked if the agents investigating Clinton could "see their way to marking the email unclassified." The agents refused.

"A senior State Department official's attempt to pressure the FBI to hide the extent of this mishandling bears all the signs of a cover-up," Ryan added.

Another FBI official told Kennedy that he would "look into" the email issue if Kennedy could raise the number of FBI personnel allowed to operate in Iraq — although the agency notes emphasized that the official made that offer "not yet knowing the email's content." No deal was made.

"These documents further demonstrate Secretary Clinton's complete disregard for properly handling classified information , Ryan said.
