This appears to be the situation in the U.S. at the moment:
1. Customs is not interested in detaining medications, especially doctor prescribed, life-saving medication that is unaffordable in the U.S.
2. FedEx basically preclears everything shipped using their service before it leaves the origin country. If it doesn't clear,it goes back to the shipper. The shipper can then refund the buyer. Other shippers probably do the same.
3. The FDA doesn't appear to be willing to intercede either at this point concerning these particular medications. Both Customs and the FDA are part of the executive branch. Right now, it looks like their next boss will probably be Hillary Clinton, who has gone on record as saying she intends to deal with pharmaceutical price gouging.
4. The Republicans are against more government regulation and interference in peoples' lives.
5. The Democrats believe in accessible, affordable health care for all.
I think if medicine were being detained at the border, we would be hearing about it. If a person has their meds detained, I think a letter from their doctor and a prescription would quickly get them undetained. Gilead is not very popular anywhere right now. Their money spends, but it is viewed as "blood money" by many in power.
The pipeline is open. We need to start using it. If someone tries to shut it down, we all need to scream bloody murder.
