The president and vice president should be legally required to either put their assets in a blind trust or make a disclosure every time government business creates a conflict of interest with their finances. Just because recent presidents have used blind trusts doesn’t mean all will willingly do so.
Avoiding conflicts of interest is a desirable goal, but Congress shouldn’t be placing restrictions on how the president and vice president manage their financial assets. Besides, the number of genuine conflicts of interest that could arise because of actions taken by the president is small.
