"Among all the foreign intelligence agencies, Russian intelligence (SVR) has a long history and has made a science of studying the backgrounds of American presidents. Therefore, we must assume that since Russian intelligence is particularly skilled and a persistent practitioner of this art, it is possible to the point of certainty that, using all their resources and "black-bag" tactics, they have long had the biographical background data that President Obama and his team of lawyers have been so diligent in concealing from the American public.
The Russians most likely would have started collecting data during Obama's university years, when he professed radical Marxist views. They were certainly focusing on him by the time of his celebrated speech at the 2004 Democratic National Convention.
By that time, Russian intelligence had easy access to the true facts concerning Obama's birth, parentage, and childhood; his mentor (communist Frank Marshall Davis); and his college performance, as well as who provided his finances. They also would have obtained the information on his passport history and his complete political career and associates.
It is recognized that among all the intelligence agencies, Russian intelligence is the most skillful in looking for information and points of leverage -- which are then exploited cleverly and "gently" by Russian statecraft." [American Thinker]
