The Democratic-controlled House of Representatives had asked the court to put off arguments scheduled for December 2, and the court on Friday agreed, removing the case from its calendar. It's not immediately clear if the arguments will be rescheduled for a later date or have been dropped altogether.
"A new Congress will convene in the first week of January 2021, and President-elect [Joe] Biden will be inaugurated on January 20, 2021", House General Counsel Douglas N. Letter wrote. "Once those events occur, the newly constituted committee will have to determine whether it wishes to continue pursuing the application for the grand-jury materials that gave rise to this case".
A Supreme Court spokesperson did not immediately return a request for comment.
Acting solicitor general Jeffrey B. Wall, responding on behalf of the Trump administration that had asked the court to take up the case, said he had no objection to the delay.
The judiciary committee has been fighting for the redacted grand jury materials since summer 2019 as part of its investigation into Russian electoral interference in the 2016 US presidential election and potential collusion with the Trump campaign.
Several top Trump aides testified before Mr.
Mueller's team found insufficient evidence to conclude that the Trump campaign conspired with Russian Federation and neither exonerated nor accused Trump of obstructing justice - writing in its report, "If we had had confidence that the president clearly did not commit a crime, we would have said so".
The material initially was sought in the summer of 2019 as part of the committee's investigation of possible misconduct by Trump, including whether he obstructed Mueller's investigation. A 448-page report issued by Mr. The Justice Department said it was prepared to proceed with the hearing but said it would accept the Supreme Court's decision.
The Justice Department argued earlier this year that the committee needs a court order to see the materials - and even with that, without a judicial proceeding, they could only see redacted versions of the documents.
Democrats claimed the materials could be used in a Senate impeachment trial, which has akin to a court proceeding.
