Lawyers for David Hearn, a former Olympian who was cleared of vandalism charges related to the Lincoln Memorial Reflecting Pool, have called for an internal inquiry into the conduct of senior officials at the Justice and Interior Departments. In a letter sent to the inspectors general of both agencies on Tuesday, Hearn’s legal team accused prosecutors of pursuing charges despite being aware that the pool’s deteriorating liner resulted from a faulty renovation.

The lawyers allege that officials disregarded evidence pointing to the botched renovation, which was overseen during President Donald Trump’s administration, and instead proceeded to indict Hearn to satisfy the former president’s demand for criminal charges. They also assert that prosecutors provided the court with false information about when they became aware of the liner’s failure.

“Due to actions by various Department of Justice and Department of Interior employees, Mr. Hearn was unjustly indicted, threatened with up to 10 years of incarceration, and suffered defamation by high-ranking government officials,” the letter states. Among those requesting the investigation is Michael R. Bromwich, a former Justice Department inspector general.

A spokeswoman for the Justice Department inspector general declined to comment, and representatives for the Interior Department inspector general and the office of Jeanine Pirro, the U.S. attorney in Washington, did not respond to requests for comment. Pirro has defended the prosecution, attributing delays in evidence sharing to the Interior Department.

However, Hearn’s lawyers challenge that account, citing evidence that prosecutors had knowledge of the pool’s liner failure weeks before Hearn’s indictment. They point to a June 30 damage assessment, received by prosecutors on July 1, which detailed damage dating back to June 8—more than a week before Hearn’s visit to the pool on June 19. Prosecutors reportedly shared this document with Hearn’s lawyers on July 10, predating the government’s claim that it first learned of the liner problems on July 17.

The case unraveled quickly after Hearn’s arrest. He was taken into custody after National Guard troops observed him interacting with the Reflecting Pool liner, which was already peeling. He was charged with damaging the liner, accusations he denied, insisting he only touched parts that were already torn.

The indictment was dropped weeks later on the basis of new information about preexisting damage to the pool liner. The decision drew sharp criticism from President Trump, who publicly condemned U.S. Attorney Jeanine Pirro’s choice to dismiss the charges and reiterated allegations of vandalism, despite the developing evidence.

Last week, a judge barred prosecutors from refiling charges against Hearn without explicit court approval, citing concerns that political pressure from the White House could drive unwarranted prosecutions. The court expressed skepticism over the merits of the case and sought to prevent further legal action absent new, substantial evidence.
