The claim that Trump said there were two whales washed up in New England over 50 years and 14 last summer, possibly due to a wind farm, cannot be verified with the provided sources.
Trump: "In New England, for 50 years they had two whales washed up. And last summer they had 14 washed up. Now, I'm not saying that's the wind farm that was built, but maybe it is. Probably is."

What the Evidence Shows
The claim attributes a specific statement to Donald Trump regarding whale strandings in New England and a possible link to a wind farm. The search results and structured sources include general information about Trump, his news updates, and a transcript of a campaign event in New Hampshire, but none of these sources contain the quoted statement or any direct reference to whale strandings or wind farms.
Without a direct transcript, video, or credible news report confirming that Trump made this statement, it is impossible to verify its authenticity. Additionally, no scientific or environmental data is provided in the sources to confirm or refute the numbers of whales washed up or any connection to wind farms.
Therefore, based on the available information, the claim remains unverifiable.
