Claim: The entire National Science Board was fired by Trump.

The claim that the entire National Science Board was fired by Trump is mostly true. Reports indicate that Trump terminated all 22 current members of the National Science Board, which is a significant action against a key oversight body for the National Science Foundation. Critics have condemned this move, suggesting it undermines scientific integrity and innovation. However, there are nuances regarding the total number of board members, as the board has 25 members in total, with 24 appointed by the president, leading to some ambiguity in the claim's phrasing. The models diverge sharply — treat this as higher-uncertainty. Perplexity comes in highest (95%), while Gemini is lowest (50%). Perplexity expresses higher confidence than Gemini on this claim. While the majority of sources confirm that Trump fired all 22 current members of the National Science Board, the claim's wording regarding 'the entire board' could imply a misunderstanding of the total membership. Some sources emphasize that the board consists of 25 members, which includes the director. This detail does not fundamentally alter the core of the claim but introduces a slight ambiguity regarding the total number of members affected. Therefore, while the claim is mostly true, the precise wording could lead to confusion about the total membership count.
