How to communicate college's financial problems to faculty candidates?
As a member of the search committee, and as a department in general, you want to aid the department in getting the best candidate possible. Misleading the candidate and losing them after the campus visit, or even after a few years, hurts the department. Doing the right thing may have long term benefits but might cause short term problems.

I would pass this off to a higher up. If you are not on the search, ask them how they are dealing with it. If you are on the search committee ask the chair of the search and/or the chair of the department. Once you get to the university level, they should be able to produce some numbers that presents the university in the best light. While this seems like it is deceiving, what you basically want to do is convince the candidate that whatever they have heard in the news, there is still a good reason to think the university will pull through the difficulties.
