A congressional committee has voted to summon US Attorney General Pam Bondi to testify about the investigation into convicted sex offender Jeffrey Epstein.

The motion to subpoena Bondi was introduced by Nancy Mace, a Republican lawmaker, who accused the justice department of a "cover-up".

The Trump administration has faced growing pressure across the political spectrum to release all of the documents related to the probe.

"The Epstein case is one of the greatest cover-ups in American history. His global sex trafficking network is larger than what is being revealed," Mace wrote on social media.

Bondi and the Trump administration have faced criticism over their handling of the release of the files, including failing to black out the names of Epstein's victims.
