Former Sen. Al Franken on Friday broke a month-long silence on social media to reveal that he and his former colleague, Sen. Pat Leahy (D-VT), were the two lawmakers who asked the FBI to investigate Attorney General Jeff Sessions’ repeated false statements under oath about his interactions with Russia.

Writing on Facebook, Franken discusses the multiple false statements and omissions that Sessions gave during testimony before the Senate about his knowledge of the Trump campaign’s efforts to contact Russian government officials.

He then reveals that he and Leahy were so concerned with Sessions’ pattern of making false statements that they asked the FBI to look into the attorney general to see if he had perjured himself.

“Nearly one year before Attorney General Sessions fired Andrew McCabe… Mr. McCabe oversaw an investigation into whether Attorney General Sessions… lacked candor when he repeatedly misrepresented his contacts with Russians when testifying before Congress,” he writes. “That investigation was opened after my former colleague, Senator Pat Leahy, and I wrote to the FBI last year and requested that the Bureau examine the attorney general’s false statements.”

Franken then said he felt disturbed by the fact that Sessions decided to fire McCabe even though McCabe had launched an investigation against him.

“That the attorney general would fire the man who was tasked with investigating him raises serious questions about whether retaliation or retribution motivated his decision,” he writes. “It also raises serious questions about his supposed recusal from all matters stemming from the 2016 campaign.”
