Blue Texan seems to assert that Larry Summers is a Goldman Sachs alumnus. This is simply a false claim on a simple matter of fact.
Blue Texan is certainly asserting that the Obama administration currently employes a Goldman Sachs alumnus. I wouldn't be surprised if there is some deputy assistant secretary of the Treasury who worked for Goldman Sachs. I wouldn't even be shocked if there is some civil servanat who briefly worked for Goldman Sachs.
