One would think that President of the United States would have multiple levels of support to keep his campaign protected from criminals and con artists. Unfortunately, based on the article below, it would appear that such characters have donated some of their ill gotten gains to his re-election campaign.
The lesson is quite simple; do not use “good judgment” or a recommendation alone when dealing with new people or businesses. The means of checking on background of a company or individual are available to everyone and at very affordable prices. The small cost and time required to uncover that these donors were trouble would have been well worth the prevention of this embarrassment.
