Former US Vice President Mike Pence gave up the sensitive materials to the FBI after they were found at his Indiana home last week, according to letters from his attorney obtained by Reuters on Tuesday.

The National Archives received notice of the records from the lawyer, Greg Jacob, on January 18; on January 22, the Archives received notice that the FBI had visited the former vice president’s house to collect the documents.

The discovery puts Pence in the company of his former boss, former President Donald Trump, and President Joe Biden after documents with classified markings were found at their residences.

Jacob said in the letter dated Jan. 18 to the National Archives that “out of an abundance of caution” Pence had engaged outside counsel to review records stored in his home after reports about the materials found at Biden’s residence.

In a separate letter dated Jan. 22, Jacob said the Justice Department “bypassed the standard procedures and requested direct possession” of the documents at Pence’s residence.

With agreement by the former vice president, FBI agents came to his Indiana home at 9:30 p.m. on Jan. 19 to collect the documents stored in the safe, Jacob said.

Biden, whose documents dated from his time as vice president, and Trump, who resisted turning over the items, leading to an FBI raid, are both facing special counsel investigationsby the Justice Department over improper handling of classified materials.

During a presidential transition period, the records from each administration are supposed to be turned over to the legal custody of the U.S. National Archives. It is unlawful to knowingly or willfully remove or retain classified material. Failure to properly store and secure classified material poses risks to national security if it should fall into the wrong hands.
