[Grammar] Regarding a use of conjuction

[Joe333]

Sentence: "More than allegations and politics I am interested in knowing whether Goldman Sachs's director Rajat Gupta really made the money through insider trading or one of them paid on his behalf"


My question/doubt: Is the use of conjunction "whether" right in the above mentioned sentence ? Or the sentence would do without it ?


Thanks

This is possible (among other rephrasings):
"More than allegations and politics, I am interested in knowing whether Goldman Sachs's director Rajat Gupta i) made the money through insider trading or ii) was paid directly by Goldman Sachs."

As Gillnetter implies, your "whether" doesn't carry over to your last
clause.
