Former President Trump’s trial stemming from Special Counsel Jack Smith’s 2020 election interference investigation has been delayed indefinitely, Fox News has learned.

The trial was set to begin on March 4 — a day before the critical Super Tuesday primary contests, when Alabama, Alaska, American Samoa, Arkansas, California, Colorado, Maine, Massachusetts, Minnesota, North Carolina, Oklahoma, Tennessee, Texas, Utah, Virginia and Vermont vote to select a GOP nominee.

Washington, D.C., federal Judge Tanya Chutkan on Friday formally vacated the March 4 trial date, saying the court will “set a new schedule if and when the mandate is returned.”

A federal appeals court is considering Trump’s claim of presidential immunity from prosecution for his actions in office. A ruling from that court is expected, and the Supreme Court may eventually review the issue.

The delay comes after Smith in December asked the Supreme Court to rule on whether Trump can be prosecuted on charges relating to his efforts to overturn the 2020 election results.

Additionally, lawyers for Trump filed a motion urging Chutkan to pause proceedings against Trump in the Jan. 6 case while his appeal is pending.

Chutkan said in December that she does not have jurisdiction over the matter while it is pending before the Supreme Court, and she put a pause on the case against the Republican 2024 front-runner until the high court determines its involvement.

Smith charged the former president with conspiracy to defraud the United States; conspiracy to obstruct an official proceeding; obstruction of and attempt to obstruct an official proceeding; and conspiracy against rights. Those charges stemmed from Smith’s investigation into whether Trump was involved in the Capitol riot on Jan. 6, 2021, and any alleged interference in the 2020 election result.

Trump pleaded not guilty to all charges in August 2023.
