Sen. Amy Klobuchar (D-Minn.) wants to know whether the Department of Justice informed the Federal Election Commission when it reviewed a referral based on a whistleblowers complaint that President Donald Trump may have violated campaign finance laws by pressuring Ukraine President Volodymyr Zelensky to open investigations into his political rivals .

In a letter to the three FEC commissioners sent Wednesday, Klobuchar, a presidential candidate, asked whether the Department of Justice violated a 42-year-old agreement to share information about campaign finance-related legal matters with the FEC after it determined that Trump had not broken the law.

The Justice Departments failure to inform the FEC is potentially a third cover-up of Trumps abuse of power after he pressured Zelensky on July 25 to open an investigation into former Vice President Joe Biden , a 2020 presidential candidate, Georgetown Law School professors Neal Katyal and Joshua Geltzer argued in a New York Times op-ed on Wednesday. The first two cover-ups, they argue, were the efforts to hide a record of the phone conversation on a code-word classified server and then the refusal of the acting director of national intelligence to send the whistleblowers complaint to congressional intelligence committees as required by law.

Klobuchar, as the ranking member of the Senate Rules Committee, which has jurisdiction over federal elections, wants to know whether the Justice Department ever informed the FEC that it had reviewed a campaign finance legal matter regarding the president and declined to prosecute it and whether the FEC agreed with the DOJs determination that Trumps actions did not violate the law.
