A government watchdog says the Commerce Department is trying to block the findings of an investigation into the agency’s role in rebuking forecasters who contradicted President Donald Trump’s inaccurate claims about the path of Hurricane Dorian last year. The accusation comes from Peggy Gustafson, the inspector general for the Commerce Department, who wrote a memo expressing “deep concern” that release of the report was being blocked. It’s the latest turn in a saga that led the National Oceanic and Atmospheric Administration to chastise government forecasters who contradicted the president after he posted inaccurate information about the hurricane’s path across the southern United States.
