There is no verified public evidence to suggest that María Corina Machado, a Venezuelan opposition leader, works with the CIA. Claims about such partnerships are often part of political rhetoric and propaganda, particularly in highly polarized environments like Venezuela. 

María Corina Machado is known for her strong opposition to the Venezuelan government, particularly under Hugo Chávez and Nicolás Maduro. She has been a vocal advocate for democracy and human rights in Venezuela and has faced significant political persecution as a result.

If you have specific concerns or need detailed information, it's always best to consult credible sources and verified reports.
