(B) Defendant’s Written or Recorded Statement. Upon a defendant’s request, the government must disclose to the defendant, and make available for inspection, copying, or photographing, all of the following:

(E) Documents and Objects. Upon a defendant’s request, the government must permit the defendant to inspect and to copy or photograph books, papers, documents, data, photographs, tangible objects, buildings or places, or copies or portions of any of these items, if the item is within the government’s possession, custody, or control and:

(v) Signing the Disclosure. The witness must approve and sign the disclosure, unless the government:

• states in the disclosure why it could not obtain the witness’s signature through reasonable efforts; or

• has previously provided under (F) a report, signed by the witness, that contains all the opinions and the bases and reasons for them required by (iii).

(vi) Supplementing and Correcting a Disclosure. The government must supplement or correct its disclosures in accordance with (c).
