Joe Biden formally asks Secretary of Senate to search for Tara Reade complaint

Joe Biden sent a letter to the Secretary of the Senate on Friday asking for a search of his records to try to locate a sexual harassment complaint that Tara Reade allegedly made in 1993 about Biden.

Why it matters: In the letter, Biden goes farther than just asking to release a complaint if it exists — he asks to make public "all other documents in the records that relate to the allegation."

• Biden said that he would do this when he addressed Reade's allegations for the first time this morning in a statement and subsequent TV interview with MSNBC's "Morning Joe."

What they're saying: "I request that you take or direct whatever steps are necessary to establish the location of the records of this Office, and once they have been located, to direct a search for the alleged complaint and to make public the results of this search," Biden wrote in the letter.

• "I would ask that the public release include not only a complaint if one exists, but any and all other documents in the records that relate to the allegation."

Go deeper: Some Democrats want more from Biden on sexual assault allegations.
