A PROBE has been launched into Donald Trump prosecutor Jack Smith for “illegal political activity”.

Smith, the former special counsel, investigated then-candidate Trump before his reelection to a second term.

The Office of Special Counsel, an independent federal agency, on Saturday confirmed the investigation.

Trump was slapped with a federal indictment in 2023 over allegations he tried to overturn the 2020 election.

It was one of four indictments leveled against the president-elect after he left office in 2021.

Trump was charged with conspiracy to defraud the US, obstruction and conspiracy to obstruct, and conspiracy against rights.

The case never made it to trial before the presidential election and was subsequently dropped following Trump’s victory.

However, Smith’s findings were published just one week before Trump’s inauguration, when he will be sworn in as the 47th president.

Smith’s report claimed Trump tried to retain power after losing to Biden by “using fraud and deceit.”

He also claimed Trump pressured election officials at the state level in a desperate bid to try and change the results.

Trump was also said to have pressured then vice-president Mike Pence, who was President of the Senate, to change the election result, according to the report.

Smith revealed that his team had “admissible evidence,” which he believes would’ve helped them get a conviction against Trump – had he not won the 2024 election.

“The department’s view that the Constitution prohibits the continued indictment and prosecution of a president 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 office stands fully behind,” the report said.

Trump vehemently denied any allegations of election interference following his indictment.

Trump took to Truth Social after Smith’s report was released. 

In one post, he labeled Smith as “deranged and a lamebrain.”

The 170-page dossier contained a letter Smith had penned to Merrick Garland, the Attorney General.

Smith described Trump’s claims that his actions were influenced by the Biden administration as “laughable.”

“It is equally important for me to make clear that nobody within the Department of Justice ever sought to interfere with, or improperly influence, my prosecutorial decision-making,” he said.

On Monday, Trump filed a desperate appeal to try and stop Smith’s report from being released.

But Aileen Cannon, a district judge, didn’t rule in Trump’s favor.

Smith shelved Trump’s election interference case following the tycoon’s landslide win in November.

Trump stormed to victory, sweeping the crucial battleground states and becoming the first Republican presidential candidate in 20 years to win the popular vote.

At the time, Smith referred to the Justice Department policy that shields presidents from prosecution.

The case was dismissed without prejudice, meaning charges could be leveled against Trump when he leaves office.
