Kentucky Sen. Rand Paul is instituting new approval and citation rules for his staffers and researchers as he faces accusations of plagiarism.
Paul initially tried to downplay revelations first reported by MSNBC that he had used material from Wikipedia without attribution.
Since then, more accusations have surfaced about material in his book and his weekly column in The Washington Times. The newspaper has since dropped the column.
Paul adviser Doug Stafford says the office now plans to make footnotes available on request, and will seek to make attribution to other people's work more complete.
