The Senate Judiciary Committee has learned that an investigation into former Attorney General Loretta Lynch may contain a deeper hold than suspected.

A recently uncovered document shows Lynch had told Hillary Clinton's campaign director, Amanda Renteria, that she “would not push too deeply” into the FBI investigation on Clinton's private email server during her bid for the presidency.

The committee is now asking whether Lynch or her aides were in touch with former DNC chair Debbie Wasserman Schultz regarding the investigation. It is also asking why she dismissed former FBI Director James Comey when he asked her about the document.

Lynch's attorney is denying the allegation, which Politico claims is “fueled by a Russian intelligence memo that's credibility has been called into question.”

“Ms. Lynch does not know Ms. Renteria, did not discuss the Clinton email investigation with Ms. Renteria, and did not communicate to Ms. Renteria, either in words or in substance, that ‘she would not let the FBI investigation into Clinton go too far,’" her attorney, Robert Raben, wrote to Judiciary leaders.

Raben continued by insisting Lynch did not discuss the Clinton probe with Clinton's campaign manager or with anybody within the DNC.

The document was found as part of a three-page list of questions that Senate Judiciary Chairman Chuck Grassley and California Senator Dianne Feinstein sent to Lynch asking about the Russian intelligence memo. The same memo surfaced in April when Comey had publicly announced he decided to not press criminal charges against Clinton.

Lynch insists that she does not “recall.”
