Federal prosecutors continue to build a case that the former president obstructed efforts by the government to reclaim classified material and that he may have misled his own lawyer.
At issue is whether prosecutors have sufficient evidence of a crime to force a lawyer for Donald J. Trump to testify to a grand jury and turn over documents related to his representation of the former president.
Prosecutors have asked a federal judge to set aside any claims of executive privilege that former Vice President Mike Pence might raise to avoid answering questions.
Prosecutors have combed through more than 100,000 documents from John Eastman, Jeffrey Clark and Ken Klukowski, who played roles in the effort to reverse the outcome of the 2020 election.
The department wants the court to force a representative of Donald J. Trump to swear under oath that there are no more classified documents at any of his properties.
