I'll make this brief. The unsealed motion had to do with Maxwell's recently rejected motion for release on bail. It had been sealed because it references documents that are still under seal. You can read the full motion for release on bail here.
I won't go through the whole motion - only the parts that stand out.
First, Maxwell makes the accusation that "the government concedes it cannot establish that either Ms. Maxwell or Epstein ever caused, or sought to cause, Accuser-3 to travel while she was a minor or that she was underage when she allegedly engaged in sex acts with Epstein."
In support of this claim, Maxwell's lawyers cite to the still-sealed filing by the government.
