On Saturday night, Former President Donald Trump tried to distract from his own legal problems over government documents by claiming his arch enemy Hillary Clinton crammed classified information on to a 'secret serverOn Tuesday, she hit back with an exasperated tweet.
I can't believe we're still talking about this, but my emails… As Trump's problems continue to mount, the right is trying to make this about me again,' wrote the former secretary of state.
'There’s even a "Clinton Standard."
'The fact is that I had zero emails that were classified.'
An FBI investigation in 2016 concluded that she and her aides were 'extremely careless' in their handling of classified information - and that classified information was in emails sent and received by an address she maintained on a non-government server.
But then director James Comey said 'no reasonable prosecutor would bring such a case
He later rowed back and said there was very little secret information. And subsequent investigations found none of the emails in question carried 'classified' markings.
Her opponents have put the episode back in the news in recent days as they try to defend Trump.
FBI agents found more than 11,000 government records at his Mar-a-Lago home last month, including highly sensitive classified documents.
During a rally in Pennsylvania on Saturday he claimed it was all part of an effort to silence him.
'Even media companies that are pretty far left have come out and said we can't believe this is happening in the USA,' he told thousands of supporters in Wilkes-Barre.
'We are being assaulted by the same groups, the FBI and DOJ, that just a few years ago declared no reasonable prosecutor would charge Crooked Hillary after she set up a secret illegal server to hide her family's pay-for-play schemes.
'Crammed full of classified information, allowed it to be plundered by foreign hackers. You know that happened? And then deleted 30,000 emails, think of that.'
His supporters broke into a chant of 'lock her up,' a common refrain during the 2016 election when her emails - and the FBI's decision to reopen its investigation - overshadowed the final days of campaigning.
This time around it is Trump facing legal jeopardy, and Clinton has leaned into the story amid allegations that the former president may have tried to obstruct the investigation.
Even before the Mar-a-Lago raid she highlighted reports that Trump destroyed records by tweeting a link to her political action committee and its collection of 'but her emails' stickers, mugs and T-shirts.
Clinton waded back in on Tuesday with a tweet thread.
