Prominent U.S. Sen. John Cornyn wants answers from Attorney General Loretta Lynch about a report from CNN that the Justice Department “pushed back” against opening a public corruption case into the Clinton Foundation, as recommended by the FBI.

In a letter sent to the attorney general Friday, the Texas Republican reminded Lynch she followed FBI Director James Comey’s recommendation not to pursue charges against Clinton over her use of a private email server while going against the agency in pursuing possible criminal charges regarding the Clinton Foundation.

“The practice is not clear, but the outcome in both cases favors Secretary Clinton,” Cornyn wrote.

“This contrast does little to instill faith in the Department, part of why I called for an appointment of the Special Counsel in the email matter. But greater clarity for the public on the basis for your decision may,” he added.

Emails obtained through FOIA requests by the conservative watchdog group Judicial Watch showed a blurring of the lines between the State Department and the Clinton Foundation while Clinton served as secretary of state.

And Cornyn is concerned about the possibility of “abuse.”

“This kind of conduct is unacceptable, and reflects the worst concerns harbored by the public about the abuse of government office to benefit the powerful at the expense of the American people,” he said in the letter. “It violates the commitment Secretary Clinton made to Congress and the executive branch following her nomination to be secretary of state.”

Cornyn asked Lynch to confirm whether the CNN report is accurate and hit the attorney general with a series of questions, as seen here:

When did the FBI recommend that the Department open a case and pursue criminal charges related to the Clinton Foundation? Why did the FBI recommend that the Department open a case on the Clinton Foundation? Which Department employees, in the Public Integrity Unit or elsewhere, were involved in the decision not to open a case on the Clinton Foundation? In the earlier reported investigation by the Department, which violations of criminal law were considered? And why did the Department decide not to open a case? In your recent private meeting with former President Bill Clinton, did you discuss anything regarding the Clinton Foundation? If so, please indicate what was discussed.

Team Hillary fell back on an oldie, but goodie in responding to the letter — the vast right-wing conspiracy theory.

“The right-wing organization behind this lawsuit has been attacking the Clintons since the 1990s, and no matter how this group tries to mischaracterize these documents, the fact remains that Hillary Clinton never took action as secretary of state because of donations to the Clinton Foundation,” Clinton campaign spokesman Josh Schwerin said in a statement.
