I want to know the answer to the following question:
Controversy regarding these accusations has caused conflict with how many presidential administrations?
All the background I'm provided with is that "Controversies regarding these claims have resulted in a sometimes shaky relationship between the organization and three presidential administrations, that of Ronald Reagan, George H. W. Bush and George W. Bush, withholding funding from the UNFPA.". Is that enough to answer the question?
Answer: yes
