What the Evidence Shows
The claim that Robert F. Kennedy Jr. Has unveiled an ambitious plan to fit every American with a tracking device within the next four years is based on his public statements as Health and Human Services Secretary promoting widespread use of wearable health-tracking devices.

Kennedy’s proposal focuses on encouraging voluntary adoption of commercially available fitness and health trackers to empower individuals to monitor their health metrics, not forcibly implanting or fitting tracking devices on all citizens.the-express.comthe-express.comRFK Jr. wants every American to wear 'health tracking' device by 2029 - US News... The devices are described as wearables like smartwatches or fitness bands that track health data such as heart rate and glucose levels. There is no credible evidence that Kennedy or the administration plans to forcibly fit tracking devices on Americans or that these devices would be used for government surveillance beyond health monitoring purposes.
Thus, while the core factual element, that Kennedy wants widespread wearable use within four years, is accurate, the framing of 'fitting every American with a tracking device' can be misleading if interpreted as compulsory or invasive government tracking.
