Does Roberts have memory problems?

Washington Post:

Over the weekend, The Post obtained a copy of the Federalist Society Lawyers' Division Leadership Directory, 1997-1998. It lists Roberts, then a partner at the law firm Hogan & Hartson, as a member of the steering committee of the organization's Washington chapter and includes his firm's address and telephone number.

Yesterday, White House spokeswoman Dana Perino said Roberts "has no recollection of being a member of the Federalist Society, or its steering committee." Roberts has acknowledged taking part in some Federalist Society activities, Perino said.

He was a member of a steering committee and doesn't remember being a member of the organization? Can we have a neuopsych eval please?
