Hillary Clinton should probably watch her back.

GOP insiders are actively working to hunt down transcripts of Clinton’s paid speeches to Wall Street’s biggest banks like Goldman Sachs, according to a report by the Hill.

Clinton gave three speeches in 2013 to Goldman Sachs at $225,000 a speech, all of which Sen. Bernie Sanders has called her out for, demanding she release the transcripts of those speeches.

Clinton has refused, leaving GOP operatives to try to piece together in a secret mission, just what exactly Clinton told the big bank that earned her such a hefty paycheck.

One GOP operative working on the case said finding and exposing the transcripts “would be a heck of a way to outflank Hillary on her left [in a general election] and stop Bernie’s supporters from voting for her.”

“Just mail the Goldman Sachs transcripts to every Bernie supporter. There’s your targeted mail program right there,” the operative continued.

A number of employees at Goldman Sachs at the time Clinton gave the speeches have cooperated with GOP operatives to find out what was in those speeches, but all they are able to piece together are “vague recollections” of the speeches, according to a source close the Hill.

No major operatives have been able to get full detailed notes about Clinton’s speeches yet, with one GOP official saying the speeches “falls into the space of we believe it exists, but there’s no route to get to the information without Hillary Clinton releasing it herself.”

Multiple sources with the Hill said they are frustrated by how little of the speeches they have found considering some attendees could have recorded segments on smart-phones or even taken notes.

“I won’t say it won’t come out at some point,” said another GOP operative investigating the speeches. “It’s like a bomb that’s going to go off in the general election.”

When Clinton gave the speeches to Goldman Sachs, she signed a contract which demanded that the speeches not be video-recorded and that the transcripts of the speeches only be in her possession. Her campaign has never disputed the terms of the contract.
