Joe Biden is at the center of a sexual assault fire storm.
He has been accused of sex assault by former staffer Tara Reade.
Reade says she filed a complaint with a personnel office on Capitol Hill around 1993.
CNN says Reade doesn't have a copy of the document.
She doesn't remember where and to whom, specifically, she filed it.
Biden has denied the assault.
He has asked the National Archives and the Secretary of the Senate to find any document and make it public.
On Monday Julie Adams, the secretary of the Senate, released a statement on Monday that makes clear she can't legally do what Biden is asking.
"The Secretary has no discretion to disclose any such information as requested."
