Washington: As Hillary Clinton turned over her private server to Justice Department amid reports it contained ‘top secret’ emails, Bobby Jindal said she is just a single email away from serving prison time.

Now that the Democratic frontrunner presidential contender has asserted that she’s turned over all of her emails, any breach would mean she’s lied in court proceedings, her long shot Republican rival and Louisiana Governor Jindal said.

‘She’d better pray the Chinese government doesn’t do a document dump,’ Jindal said in remarks released by his campaign.

Jindal’s remarks came as Clinton relented Tuesday to months of demands to relinquish the personal email server she used while serving as secretary of state.

Clinton campaign spokesman Nick Merrill said she has ‘pledged to cooperate with the government’s security inquiry, and if there are more questions, we will continue to address them.’

Clinton’s emails have been under scrutiny since it was revealed that she used a private server in her home to send and receive messages when she was secretary of state.

The FBI has been looking into the security of the private server and investigators have been trying to determine whether Clinton sent or received classified information on an unsecured system.

Meanwhile, Chuck Grassley, the Republican chairman of the Senate Judiciary Committee said Tuesday two of the four classified messages discovered in emails turned over to the State Department by Clinton were labelled ‘top secret.’

The inspector general for US intelligence agencies had reported that two of the emails not only were classified but were in fact categorized as ‘Top Secret, Sensitive Compartmented Information’ — one of the strictest security classifications, he said.

Clinton’s turning over of the server is ‘a welcome development,’ he said, but he declared: ‘That’s a long time for top secret classified information to be held by an unauthorised person outside of an approved, secure government facility.’

Clinton aides have maintained that nothing on her server was classified at the time she saw it, suggesting that classified messages were given the label after the fact.

State Department spokesman John Kirby said Tuesday that was the case with two emails, adding that it remained unclear ‘whether, in fact, this material is actually classified.’

‘Department employees circulated these emails on unclassified systems in 2009 and 2011, and ultimately some were forwarded to Secretary Clinton,’ he said. ‘They were not marked as classified.’
