I'm not sure why this is a big deal especially when it has such scientistific value
In the US, people are becoming increasingly tolerant of corruption. These days it more often invokes funny euphemisms than action. Politicians have innate incentive to fall into corruption, and it's expected that some of them do from time to time. But, it's the people's job to keep them in check.
If this country values funding science, then it should let the scientists determine where and how the money should be spent, not politicians, not lobbies.
