Yes, that’s Fred (”Gopher”) Grandy’s wife. Fred served in the House with Newt (while they were in the minority). Their wives would have been associated as members of the “Congressional Wives Club,” which is actually a pretty active group.
After leaving Congress, Fred Grandy became a very popular radio guy in DC, with occasional outspoken appearances by Mrs. Grandy, so the Grandys have long been in on the political ‘action,’ if no longer in Congress.
