After being ensnared by a series of plagiarism accusations last year, Sen. Rand Paul (R-Ky.) is facing a new claim over his lawsuit against President Barack Obama and the NSA.

In a Wednesday Washington Post column, Dana Milbank draws attention to the fact that a key name was missing from the class-action lawsuit filed by Paul: former Reagan Administration lawyer Bruce Fein, who had been working with the senator since December.

When lining up a Jan. 15 Fein draft with Wednesday’s lawsuit, the Post found the documents to be almost entirely similar, along with the insertion of a new lead counsel: former Virginia Attorney General and gubernatorial candidate Ken Cuccinelli (R). According to the Post, Fein’s camp was “aghast and shocked” over the change.
