Four Republican senators have asked that a second special counsel is appointed to investigate allegations of abuse at the Department of Justice and Federal Bureau of Investigations. Attorney General Jeff Sessions is under mounting pressure from the GOP to do so.

At issue is how the DOJ and FBI handled probes into the allegations of Russian meddling in the 2016 presidential election before special counsel Robert Mueller became involved.

The Hill reports: Up to now, those calls have gone quietly unanswered, with officials pointing to the existence of a Justice Department inspector general investigation that is expected to wrap up sometime this spring.

But Sessions last week revealed that he has tapped a former official outside of the Beltway “with many years in the Department of Justice” to review the need for a special counsel, suggesting the idea is receiving a serious look. 

In a letter sent to Sessions and Deputy Attorney General Rod Rosenstein on Thursday, Senate Judiciary Committee Chairman Chuck Grassley (R-Iowa) and Sen. Lindsey Graham (R-S.C.), Sen. John Cornyn (R- Tex.), and Sen. Thom Tillis (R-N.C.) called for a special counsel to “gather all the facts,” noting that a special prosecutor has more tools and prosecutorial power than an inspector general.

Last week, House GOP chairmen — Judiciary Committee Chairman Bob Goodlatte (Va.) and Oversight and Government Reform Committee Chairman Trey Gowdy (S.C.) made a similar request, demanding a review of any evidence of “bias” by DOJ or FBI employee as well as whether there was any “extraneous influence” on the surveillance process, according to The Hill.
