The board said in a statement that there was no evidence to suggest that the prize entries were flawed.

The reviews were done after the board heard complaints from Mr. Trump and others.

The reviews were conducted by individuals with no connection to the institutions whose work was being examined. No passages, headlines, contentions or assertions in any of the winning submissions were discredited by the facts that emerged after the conferral of the prizes.

The Pulitzer Prizes in national reporting stood.

There are links between Russian interference and Mr. Trump's campaign and administration.

Mr. Trump has called for the prizes to be revoked many times, despite his insistence that Russia did not help him win the election. He wrote in October that the coverage was based on false reports of a link between the Kremlin and the Trump campaign. The administrator of the prizes received a letter from Mr. Trump threatening to take legal action if the awards were not taken away.

A spokeswoman for The Times wouldn't comment. A spokesman for Mr. Trump didn't reply immediately.
