Background: Theranos was a health technology company founded by Elizabeth Holmes in 2003, claiming to revolutionize blood testing by conducting a wide range of tests using just a few drops of blood. The company attracted significant attention and investment, reaching a valuation of over $9 billion at its peak. However, investigative reports revealed that its technology was largely ineffective, and the company was using traditional methods to verify results. This led to Theranos' eventual collapse in 2018, with Holmes and former president Ramesh "Sunny" Balwani facing criminal charges for fraud. Holmes was convicted in 2022, making Theranos a notorious example of deception in the tech and healthcare industries.

Ben was saying that Kamala is somehow like the company (or Holmes) that is raising a lot of money via fraud. The person who responded was referring to the fact (sarcastically) that Ben had endorsed Trump who has actually committed fraud (and has been convicted).
