Special counsel Jack Smith is evaluating how to wind down the before the president-elect takes office in light of longstanding Justice Department policy that says sitting presidents cannot be prosecuted, a person familiar with the matter said Wednesday.

Smith charged Trump last year with and . But means that the Justice Department believes he can no longer face prosecution in accordance with department legal opinions meant to shield presidents from criminal charges while in office.

The person familiar with Smith鈥檚 plans was not authorized to discuss the matter by name and spoke on condition of anonymity to The Associated Press.

By moving to wind down the cases before the inauguration in January, Smith and the Justice Department would be averting a potential showdown with Trump, who that he would fire Smith 鈥渨ithin two seconds鈥� of taking office. It would also mean Trump would enter the White House without the legal cloud of federal criminal prosecutions that once carried the potential for felony convictions and prison sentences.

NBC News first reported Smith鈥檚 plans.

Smith鈥檚 two cases charge Trump in a conspiracy to undo the election results in the run-up to the Capitol riot, and with retaining top secret records at his Mar-a-Lago estate in Florida and obstructing FBI efforts to recover them.

The classified documents case has been stalled since July when a Trump-appointed judge, Aileen Cannon, . Smith has appealed to the Atlanta-based 11th U.S. Circuit Court of Appeals, where the request to revive the case is pending. Even as Smith looks to withdraw the documents case against Trump, he would seem likely to continue to challenge Cannon鈥檚 ruling on the legality of his appointment given the precedent such a ruling would create.

In the 2020 election interference case, Trump was scheduled to stand trial in March in Washington, where more than 1,000 of his supporters have been convicted of charges for their roles in the Capitol riot. But the case was halted as Trump pursued his sweeping claims of immunity from prosecution that ultimately landed before the U.S. Supreme Court.

Trump could be emboldened by the Supreme Court鈥檚 ruling in July, for acts taken in the White House and explicitly put off-limits any alleged conduct involving Trump鈥檚 discussions with the Justice Department. That included his efforts to use the Justice Department to conduct sham election fraud investigations as part of his bid to stay in power.

The conservative-majority Supreme Court sent the case back to U.S. District Judge Tanya Chutkan to determine which of the other allegations in the indictment, if any, could move forward to trial.

In response, laying out new evidence to persuade the judge that the actions alleged in the indictment were taken in Trump鈥檚 private capacity as a candidate 鈥� not as commander-in-chief 鈥� and therefore can remain part of the case. Trump鈥檚 lawyers are scheduled to file their response later this month.

In New York, meanwhile, Trump could seek to leverage his newfound status as president-elect in an effort to set aside or expunge and stave off a potential prison sentence.

Trump has been fighting for months to overturn the May 30 verdict, which involves a $130,000 hush money payment to porn actor Stormy Daniels just before the 2016 election. It is the only one of his criminal cases to go to trial.

Tried as a private citizen, his impending return to the White House could compel a court to step in and avoid the unprecedented spectacle of potentially locking up a former and future president.

Trump鈥檚 lawyers haven鈥檛 signaled their plans. Before the election, the attorneys were rejected in a bid to move the case from state court to federal court, where he could more easily dispose of it. They are now appealing.

Judge Juan M. Merchan has said he will rule next Tuesday on whether to uphold or toss the verdict in the wake of the U.S. Supreme Court鈥檚 July ruling that presidents have broad protections from prosecution.

The judge has penciled in Nov. 26 for sentencing, 鈥渋f necessary.鈥� Punishments range from a fine or probation to up to four years in prison.

Though Trump technically has no authority as president to shut down a state-level prosecution like the one in New York, his victory nonetheless calls into question that case charging him with plotting to subvert that state鈥檚 election in 2020.
