The FBI on Friday conducted a search of former Vice President Mike Pence’s home in Indiana weeks after documents with classified markings were found there, multiple outlets reported.

The search was done in cooperation with Pence’s team, which had been in touch with federal officials about it in advance. News of the search was first reported by Politico.

A Pence spokesperson did not respond to a request for comment.

Pence’s lawyer, Greg Jacob, notified the National Archives on Jan. 18 that a small number of documents with classified markings were found at the former vice president’s Indiana home. Officials had searched the home for classified documents out of an abundance of caution after sensitive government materials were found at President Biden’s home in Wilmington, Del., and his old office in Washington, D.C.

The documents were turned over to federal authorities the next day, along with two other boxes with copies of administration records, Jacob said.

Some Pence allies have expressed frustration about the handling of the situation, arguing that federal investigators were far quicker to search Pence’s home than they were to search Biden’s home.
