The government is apologizing for stopping a load of seniors returning from a medicine-buying trip to Canada.
The incident happened last October but wasn't made public until this week, when Minnesota Senator Mark Dayton wrote a letter complaining about it to the Food and Drug Administration.
An FDA spokesman says the inspection was unfortunate and not consistent with current policy.
Dayton wrote that the inspection caused stress for the elderly travelers.
The millionaire Democrat donates his entire Senate salary to pay for the bus trips from Minnesota, allowing seniors to take advantage of the much lower prescription drug prices in Canada.
The FDA says it cannot guarantee the safety of medications purchased in Canada and has been increasing pressure on state and local programs that help people buy the lower-cost medicines there.
