Amid the revelations about dozens of Obama administration requests to "unmask" Lt. Gen. Michael Flynn's conversations that were "incidentally" picked up by surveillance of other figures, just prior to multiple leaks about Flynn to the press, two Republican senators are asking for more information.
Sen. Ron Johnson (R-Wisconsin), who heads the Homeland Security Committee; and Sen. Chuck Grassley (R-Iowa), who chairs the Finance Committee, have sent a letter to Attorney General William Barr and Acting Director of National Intelligence Richard Grenell.
One of the most significant unanswered questions about what occurred during the 2016 election is how many Americans were ‘unmasked,’ at whose request, and for what purpose.Senators Johnson and Grassley, May 12, 2020 letter
The senators are asking to see "all information regarding the 'unmasking' of U.S. persons requested by members of President Obama’s administration around the time of the 2016 election through January 2017."
Read the letter below:
May 12, 2020
Ambassador Richard Grenell
Office of the Director of National Intelligence
The Honorable William P. Barr
U.S. Department of Justice
Dear Ambassador Grenell and Attorney General Barr:
Based on recent press reports, it is our understanding that you conducted a classification review and declassified information related to numerous requests to “unmask” the names of U.S. persons who appeared in certain intelligence reporting around the time of the 2016 election through January 2017.
We wholeheartedly agree that transparency is needed more now than ever. One of the most significant unanswered questions about what occurred during the 2016 election is how many Americans were “unmasked,” at whose request, and for what purpose. Your recent decision to declassify dozens of footnotes from the report of the Department of Justice’s Office of the Inspector General about the investigation of the Trump campaign; the declassification and disclosure of transcripts of related interviews by the House Intelligence Committee; and the disclosure of exculpatory information related to the prosecution of Lt. General Michael Flynn, paint a more and more troubling picture of the conduct that we have been investigating since 2017. However, we firmly believe that the best way to resolve these issues is to determine the truth, and to make clear to the American people what did and did not occur.
For these reasons, we respectfully request that you make available to us, as soon as possible, all information regarding the “unmasking” of U.S. persons requested by members of President Obama’s administration around the time of the 2016 election through January 2017.
