The former is a name authority record and the latter is an LCSH subject authority. The latter is needed in order to get the heading to display in the LCSH products, and because it is an example given under the subject heading Legislative bodies. So these are purposely duplicates.

I noticed one with the LCCN starting with "n" while the other one starting with "sh". I would really appreciate if anyone can tell me if they are just duplicates needs to be reported or there is genuine reasons that we need two authority records with exactly the same 1XX for "United States. |b Congress" as the subject authority headings.
