White House dodges on possible Clinton email hack

The White House's top spokesman sidestepped a question about whether President Obama is concerned that Hillary Clinton may have exposed sensitive information to foreign hackers while using a private email server as secretary of state.

In explaining his decision not to pursue criminal charges against Clinton, FBI Director James Comey said Wednesday that there is a possibility that hostile actors could have invaded her email communications on her private server.

Asked about the vulnerability caused by Clinton's email server, White House press secretary Josh Earnest only repeated Comey's findings.

"Well, just based on what Director Comey said publicly, I think he indicated that he couldn't say one way or the other whether or not there had been an intrusion," Earnest told reporters traveling with the president to Poland Thursday. "They did not find any evidence that there was, again, based on what he said publicly."

He was not asked whether Clinton and her top aides should retain their security clearances after the FBI found them to be extremely carless in thier handling of classified information on the private email server. Republicans have called on the administration to revoke the clearances.
