(CNSNews.com) - Sens. Chuck Grassley (R-Iowa) and Ron Johnson (R-Wis.) say FBI texts and emails “demonstrate the need to investigate leaks from agencies…other than the FBI.”

The two Republicans, in a May 6 letter, asked the inspector general of the intelligence community if he has launched an investigation into the apparent leaks, perhaps by the CIA.

“If not, please explain why not,” the senators wrote to Inspector-General Michael Atkinson.

In their letter, Grassley and Johnson quoted a December 2016 text message from former FBI counterintelligence agent Peter Strzok to Lisa Page:

Think our sisters have begun leaking like mad. Scorned and worried and political, they’re kicking in to overdrive.

“[W]ho are the 'sisters' and what does it mean to say that the 'sisters have [been] leaking like mad'?" the senators asked Atkinson. “What are they worried about, and what are they kicking into 'overdrive'?”

The senators also quoted an April 2017 email that Strzok sent to FBI colleagues concerning an article in The Guardian titled, “British spies were first to spot Trump team’s links with Russia.”

I’m beginning to think the agency got info a lot earlier than we thought and hasn’t shared it completely with us. Might explain all these weird/seemingly incorrect leads all these media folks have. Would also highlight agency as source of some of the leaks.

Grassley and Johnson asked Atkinson, “Which ‘agency’ is he referring to and why does Strzok believe the referenced news article highlights that ‘agency as [a] source of some of the leaks’?”

Meanwhile, the inspector general of the Justice Department is currently investigating alleged FISA abuses and leaks by FBI personnel, and that report is expected to come out in a matter of weeks.
