Biden said he was ‘cooperating fully and completely’ with a Justice Department review.

WASHINGTON — A second set of classified documents from President Biden’s time as vice president were discovered at a storage space in the garage of his home in Wilmington, Del., his lawyer said Thursday. The documents were the second batch to be publicly acknowledged, after the administration said this week that others had been discovered on Nov. 2 in the closet of an office at a think tank that Mr. Biden had used after leaving the vice presidency.

Here’s what to know:

• The Justice Department is conducting a review intended to help Attorney General Merrick B. Garland decide whether the facts and law merit the appointment of a special counsel, like the one investigating former President Donald J. Trump’s possession of sensitive documents and failure to return all of them. Mr. Garland was scheduled to make a statement to the news media at 1:15 p.m. In the past, he has used such appearances to announce major developments, including his appointment of Jack Smith as the special counsel to oversee investigations involving Mr. Trump.

• Mr. Biden said he was “cooperating fully and completely” with the Justice Department review, but otherwise deflected questions about the documents after delivering remarks on inflation on Thursday at the White House. A reporter asked why he would store classified papers near his Corvette, and Mr. Biden replied: “My Corvette’s in a locked garage, so it’s not like it’s sitting out on the street.” He promised to offer a more detailed accounting of the situation later.

• It was not clear how many documents were found at the home. A statement from a lawyer for Mr. Biden said lawyers discovered records with classified markings “among personal and political papers” at the residence. Most of the documents were in the garage, and a one-page document was “among stored materials in an adjacent room.”

• The documents were found after Mr. Biden’s team began a search for other official records in response to the November discovery of documents at the Penn Biden Center for Diplomacy and Global Engagement. The administration said Monday that “a small number” of documents had been found there on Nov. 2, and were retrieved by the National Archives the next morning.
