"DOJ initially refused to furnish the information, citing the ongoing special counsel investigation," the release said. "Following the conclusion of Special Counsel Robert Mueller’s probe, Judiciary Committee Chairman Lindsey Graham, Finance Committee Chairman Chuck Grassley and Homeland Security and Governmental Affairs Committee Chairman Ron Johnson are renewing the request."
The senators resubmitted a classified request for a Justice Department briefing on the annexe, according to the release.
Former FBI Director James Comey closed the probe by concluding Clinton had been careless but did not commit any crime — especially concerning laws intended to protect classified information, and the FBI never saw the classified annexe to the Inspector General report, the release said.
Shortly after exonerating Clinton, the FBI launched a counterintelligence investigation of the Trump campaign over allegations of collusion with Russia.
The resulting appointment of Muller as special counsel concluded after an investigation lasting nearly two years that no collusion had taken place, according to US Attorney General William Barr.
Russian officials have repeatedly denied interference in the US political system saying the allegations were made up to excuse the election loss of Donald Trump’s opponent as well as deflect public attention from actual instances of election fraud and corruption.
