Senate Judiciary Committee Chairman Chuck Grassley, R-Iowa, is accusing former FBI Director James Comey of removing the words “grossly negligent” from his July 2016 remarks announcing Democratic presidential candidate Hillary Clinton would not be charged with a crime for mishandling classified State Department emails.

Grassley asserts that preliminary drafts of Comey’s remarks use phrases “indicating a violation of federal statute” but the works were removed in subsequent drafts.

Grassley is demanding more information about the drafts from FBI Director Christopher Wray.

“Although Director Comey’s original version of his statement acknowledged that Secretary Clinton had violated the statute prohibiting gross negligence in the handling of classified information, he nonetheless exonerated her in that early, May 2nd draft statement anyway, arguing that this part of the statute should not be enforced,” Grassley said in a letter send Monday to Wray.

Grassley is demanding the original drafts, “including the metadata to determine who is responsible for the edits.” Grassley is also asking for all records pertaining to the reasoning behind the changes.
