A blogger named Daniel (gay) and his, um, buddy... came to the US to buy the medicines they need. The government-run system in Venezuela just cannot function. Many people in that country are suffering and dying (like AIDS patients) because of the lack of advanced or even basic medicines. It cost them about $2,500 to come to the US and get those meds, the minimum wage there is $11 a month.
Anyone in that country who wants to travel has to buy dollars from the government, often this is declined for various reasons.
