Special counsel Jack Smith moved to abandon two criminal cases against Donald Trump on Monday, acknowledging that Trump’s return to the White House will preclude attempts to federally prosecute him for retaining classified documents or trying to overturn his 2020 election defeat.

The decision was inevitable, since longstanding Justice Department policy says sitting presidents cannot face criminal prosecution. Yet it was still a momentous finale to an unprecedented chapter in political and law enforcement history, as federal officials attempted to hold accountable a former president while he was simultaneously running for another term.

In court filings, Smith’s team emphasized that the move to abandon their prosecutions was not a reflection of the merit of the cases but a recognition of the legal shield that surrounds any commander in chief.

“That prohibition is categorical and does not turn on the gravity of the crimes charged, the strength of the Government’s proof, or the merits of the prosecution, which the Government stands fully behind,” the prosecutors wrote in one of their filings.

Smith’s team said it was leaving intact charges against two co–defendants in the classified documents case — Trump valet Walt Nauta and Mar–a–Lago property manager Carlos De Oliveira — because “no principle of temporary immunity applies to them.”

Steven Cheung, Trump’s incoming White House communications director, welcomed the decision to drop the prosecutions against the president–elect, describing it as a “major victory for the rule of law.”

“The American People and President Trump want an immediate end to the political weaponization of our justice system and we look forward to uniting our country,” Cheung said in a statement.

Trump has long described the investigations as politically motivated, and he has vowed to fire Smith as soon as he takes office in January. Now he will re–enter the White House free from criminal scrutiny by the government that he will lead.

But the case quickly stalled amid legal fighting over Trump’s sweeping claims of immunity from prosecution for acts he took while in the White House.

The U.S. Supreme Court in July ruled for the first time that former presidents have broad immunity from prosecution, and sent the case back to U.S. District Judge Tanya Chutkan to determine which allegations in the indictment, if any, could proceed to trial.

The case was just beginning to pick up steam again in the trial court in the weeks leading up to this year’s election. Smith’s team in October filed a lengthy brief laying out new evidence they planned to use against him at trial, accusing him of “resorting to crimes” in an increasingly desperate effort to overturn the will of voters after he lost to Biden.

The separate case involving classified documents had been widely seen as legally clear cut, especially because the conduct in question occurred after Trump left the White House and lost the powers of the presidency.

The indictment included dozens of felony counts accusing him of illegally hoarding classified records from his presidency at his Mar–a–Lago estate in Palm Beach, Florida, and obstructing federal efforts to get them back. He has pleaded not guilty and denied wrongdoing.
