LOS ANGELES, CALIFORNIA, July 19 (Reuters) - U.S. President Donald Trump called for a review related to the ‌Federal Judicial Center's scientific reference manual in cases involving climate ‌change, writing in a Truth Social post on Sunday that the work contains "discredited" ​information that led to "huge losses" for the country.

"Our Nation's Federal Judges deserve Facts and Science, not Political Fraud and False Science on Climate," Trump posted. "With this TRUTH, I hereby order Federal Suspension and Debarment ‌Officials to review this ⁠conduct."

It was not immediately clear what "conduct" Trump wants investigated. The White House did not immediately reply to a ⁠request for comment.

Earlier this year, the U.S. federal judiciary withdrew a chapter from the newest edition of its reference manual on scientific ​evidence that ​addressed climate change after Republican state ​attorneys general argued it ‌was biased against fossil fuel companies.

The Federal Judicial Center, the judiciary's research arm, incorporated a chapter addressing climate change as part of a long-planned update of the manual, the fourth edition of which was released in December. Judges rely on the manual when grappling ‌with cases involving scientific testimony.

The section at ​issue in the fourth edition of the FJC's ​Reference Manual for Scientific Evidence ​was authored by Jessica Wentz and Radley Horton ‌of Columbia Law School and was ​drafted to "help judges ​evaluate the admissibility and weight of expert testimony and documentary evidence involving climate science."

The Federal Judicial Center jointly produced the ​manual with the ‌National Academies of Sciences, Engineering, and Medicine.
