Donald Trump took a new tack on Wednesday in his continuing critique of Hillary Clinton over her mishandling of classified material on a private email server while she was secretary of state.

He told thousands of supporters bursting the seams of an Ocala, Florida livestock arena that her attorneys – the 'total professionals' who searched her electronic messages and determined unilaterally which ones to hand over to the State Department – 'have committed a crime' by deleting 33,000 of them while they were subject to a subpoena from Congress.

'Obviously they've done a great job,' he said of the white-shoe firm Williams & Connolly. 'But that law firm should be implicated in this crime, okay?'

'They're the ones. They got rid of all this stuff! The law firm got rid of all this stuff, and they should be implicated because they have committed a crime.'

Hours later in a second rally in the town of Lakeland, he upped the ante: 'Those representatives within that law firm, that did that, have to go to jail.'

LOCK THEM UP, ESQ.? Donald Trump said that Hillary Clinton's lawyers 'committed a crime' by deleting 33,000 of her subpoenaed emails, and should be legally 'implicated'

Wednesday's remarks were the Republican candidate's first foray into the idea of holding Clinton's lawyers partially responsible for what he called 'one of the great miscarriages of justice.'

FBI Director James Comey announced in July that Clinton wouldn't be prosecuted for exposing thousands of classified or partially classified documents to hostile actors, despite satisfying the technical requirements of a section of the Espionage Act written to criminalize 'gross negligence' in mishandling classified material.

Clinton admitted in April 2015, the month after receiving a subpoena from Congress, that she had directed her lawyers to purge her homebrew email server of messages deemed to be personal in nature.

It emerged in the ensuing months that Clinton didn't vet the emails herself, instead turning over the work to her lawyers – who searched broadly for keywords and didn't read each message before deciding to delete tens of thousands.

Trump said in Ocala, Florida that deletions came 'after getting a congressional subpoena,' and noted Clinton's claim last year that the emails were related to her daughter's wedding, yoga classes, and other personal matters.

Trump criticized the attorneys for making decisions about what o keep and what to erase on their own, without judicial oversight.

'They are not supposed to say, "Oh, we got rid of most of it",' he said.

'That law firm – that I know very well, as I said – total professionals, total insiders. They got rid of 33,000. And much more than that.'

'Now if your friend sues you in a regular lawsuit, and you do that, you go to jail,' he said.

David Kendall, a longtime partner at the white-shoe firm Williams & Connolly, supervised Clinton's handling of the emails, including her response to the March 2015 subpoena.

Kendall, who did not respond to a request for comment, has represented Clinton and her husband for decades, going back to the Whitewater investigation in the 1990s.

Trump pointed the finger at Kendall and his firm without naming them. But he also complained about two boxes of printed emails reportedly lost in the process.

'What about her law firm? She's using a phenomenal law firm. I know the firm. Phenomenal law firm! They're the ones that did all this stuff!' Trump boomed.
