Maxwell, currently serving 20 years in prison for trafficking girls to the disgraced financier Epstein, will face questions from prison via videolink, in a deposition by the House of Representatives’ Oversight Committee.
No new US prosecutions are expected after the latest tranche of government files on Epstein were released.
The House Oversight Committee is investigating Epstein’s connections to powerful figures and how information about his crimes was handled.
Maxwell, however, is expected to invoke her right to not incriminate herself, guaranteed in the Fifth Amendment of the US Constitution.
The Trump administration has already come under criticism for its handling of her case.
Last year, Maxwell was moved to a minimum security prison in Texas after meeting twice with Deputy Attorney General Todd Blanche, who previously served as US President Donald Trump’s personal lawyer.
Mr Trump himself was a longtime Epstein associate, but has not been called to testify by the Oversight Committee, which is led by members of his Republican Party.
Mr Trump has not been formally accused of any wrongdoing in connection with Epstein, and he has denied any knowledge of Epstein’s crimes
