Speculation About Whether Donald Trump Has Dementia Has Been Roiling for Months
President Trump is now 79, and there's been plenty of speculation about whether he has dementia or another kind of cognitive decline.
A recent video posted by user 'mcniffed' on October 1, 2025, has sparked discussion regarding alleged political bias in Google's AI search functionality. The user, identified as William McNiff, demonstrated what he claims is a discrepancy in how Google's AI handles search queries related to the mental acuity of former President Donald Trump and current President Joe Biden. In the video, McNiff shows that a search for "is Biden having a mental decline?" generates a comprehensive AI Overview, summarizing various perspectives and reports. Conversely, when searching for "is Trump having a mental decline?", the AI Overview is stated as "not available for this search," providing only traditional web links. McNiff stated, "Google is full on fascist. They are full on bending knee to Trump." He further added, "I am fully now telling people to use other AI search platforms since Google Gemini AI and Google has been compromised." This demonstration has led McNiff to advise his followers to use alternative search engines, accusing Google of censorship and political manipulation.
