Dear Bernie,
You wrote on twitter: “The people of Venezuela are enduring a serious humanitarian crisis. The Maduro government must put the needs of its people first, allow humanitarian aid into the country, and refrain from violence against protesters.” (10:47 AM – 23 Feb 2019). You must know, Bernie, that the US is suffocating Venezuela with economic and financial sanctions, preventing even access to medicines (insulin, for example). With further related info in comment below.
