During a session of the Senate National Security Committee, on Sept. 16 several Republican congressmen approved a series of subpoenas against former FBI Director John Brennan, former FBI Director James Comey, former National Intelligence Director James Clapper, as well as other Obama administration officials regarding alleged Russian interference in the 2016 presidential campaign.

The review of the subpoenas aims to clarify the background to the so-called Hurricane Crossfire investigation into the origins of the Russian plot.

As TownHall indicated, after the subpoenas were approved,  the committee chairman, Ron Johnson, expects the testimonies will proceed, which could take place through an open or closed public hearing. The date is not yet known.

United States Attorney General for the district of Connecticut John Durham is moving forward with his investigation into the origins of the FBI’s investigation into Russia, but it is not yet known whether there will be additional charges based on his findings. For the time being, U.S. Attorney General William Barr has urged calm.

“You need strong evidence of intent, it seems to me, before you can charge that kind of crime so developing that evidence is a time consuming process. Most of the people who are mouthing off about ‘Well why aren’t these people already indicted,'” said Barr, who added, “They don’t understand the criminal justice process.”

According to Fox News, the subpoenas also include former officials such as Obama’s former chief of staff Denis McDonough, former FBI adviser Lisa Page, former FBI agent Joe Pientka, former United Nations Ambassador Samantha Power, former FBI Counterintelligence Director Bill Priestapo, and former FBI lawyer Kevin Clinesmith.

Clinesmith appeared in federal court last month and pleaded guilty to making a false statement in the first criminal case arising from the Durham’s investigation.

The committee also had subpoenas for “the production of all records” related to the original investigation of Russian interference by the FBI and the investigation of Department of Justice Inspector General Michael Horowitz.

It also authorized the process of “unmasking” James Baker, former FBI Deputy Director Andrew McCabe, Justice Department official Bruce Ohr, FBI agent Steven Somma, former US Ambassador to Russia John Teftt, former Deputy Attorney General Tashina Gauhar, according to Fox News.

In addition, the committee also planned a vote to authorize a subpoena for U.S. Ambassador to Slovakia Bridget Brink as a result of an ongoing investigation into the dealings of Democratic presidential candidate Joe Biden in Ukraine during his time as vice president, according to the New York Post.

According to the Post, during the month of August, the committee summoned FBI Director Christopher Wray to request each of the records related to the Hurricane Crossfire investigation, in addition to all the documents delivered to Horowitz.
