Paul Ryan to Formally Request That Clinton Be Denied Classified Information During Campaign

His plan follows the FBI's decision not to recommend she be indicted.

"There is no legal requirement for your to provide Secretary Clinton with classified information, and it would send the wrong signal to all those charged with safeguarding our nation's secrets if you choose to provide her access to this information despite the FBI's findings," Ryan wrote in a letter to Clapper obtained by ABC News. "I firmly believe this is necessary to reassure the public that our nation's secrets are secure."

In a news conference Wednesday, Ryan again called on Clapper to deny Clinton's access to classified information. For decades, presidential nominees have received classified briefings from the administration after the party conventions.

"I have great respect for the professionals at the FBI," Ryan wrote in the letter to Comey. "However, many people -- myself included -- struggle to reconcile the case you made against Secretary Clinton with the decision against recommending prosecution."

Clinton spokesman Brian Fallon Wednesday criticized Republicans' plans to begin their own inquiries into the FBI's investigation.

Several top Republicans have written to Comey seeking more information about his agency's investigation. Others want the House to appoint a special prosecutor to review the case.
