REPUBLICAN DONOR USED MENTALLY CHALLENGED SISTER TO FUNNEL CAMPAIGN CASH: Chad Price says Mako Medical, the fast-growing lab testing company he co-founded in Raleigh, started with frustrations he faced getting his younger sister the medical tests she regularly needed. His sister Jessica, 37, was born with a genetic condition that left her with the mental capacity of a young child. She lives with Price, who is her legal guardian, at his home in Apex. But in campaign filings, Jessica emerges as an administrative employee for Mako and a political donor, contributing $17,500 to five state or federal candidates in four states, including North Carolina. For three of those candidates, Chad Price had made the maximum contributions in his own name. Those contributions are among hundreds of thousands of dollars in campaign money flowing predominantly to Republican candidates from Chad Price and a small group of people and businesses connected to him over the past five years. During that time, Price developed deep connections with state elected and appointed officials, two of whom joined his businesses.
