Personally I would attend to give any supporting evidence, but make it clear that this is an INTERNAL issue and you are not an employee of the company so will only supply material evidence if questioned if they feel it will help resolve the matter.
There is no obligation to get involved in the clients internal affairs, but if your input assists them in some way, then why not do it?
