Former US President Donald Trump has failed to comply with a subpoena issued by the congressional committee investigating his supporters' attack on the US Capitol last year, the panel said.
The January 6 select committee announced on 21 October that it had sent a subpoena to Mr Trump requiring documents be submitted by 4 November and for him to appear for deposition testimony beginning on or about 14 November.
On 4 November, it said it had agreed to give Mr Trump an extension before producing the documents after hearing from one of his attorneys.
But the panel said then that it wanted the documents the next week and that the 14 November deadline remained in place.
"The truth is that Donald Trump, like several of his closest allies, is hiding from the Select Committee's investigation and refusing to do what more than a thousand other witnesses have done," Committee Chair Bennie Thompson and Vice Chair Liz Cheney said in a statement.
Mr Trump filed a lawsuit on Friday seeking to avoid being compelled to testify or provide any documentation to the congressional panel.
The committee has held a series of hearings as it seeks to make its case to the public that Mr Trump was largely responsible for the deadly assault on Congress while politicians met to formally declare his loss to Democrat Joe Biden.
The panel has not said how it will proceed if Mr Trump disregards the subpoena request.
