The scandal is really about the policy put in place by the Obama administration.

From the article you cited:

"Career employees were ordered to provide Secretary Janet Napolitano's political staff with information about the people who asked for records — such as where they lived, whether they were private citizens or reporters — and about the organizations where they worked. If a member of Congress sought such documents, employees were told to specify Democrat or Republican."

That's a dangerous politicization of DHS and the FOIA process and certainly goes against the spirit of "transparency" the Obama administration was voted in on.
