What kind of pressure are we talking about? Anything beyond a phone call that says "We'd like you to do this" would be illegal (blackmail, extortion, etc), and I'd bring the full weight of my law department if any member of government put tangible, material pressure on my company because of something like this. But if you just get that phone call? You ask for proof, and you wait until they bring it. And you keep going on as business as usual until you get a court order or similar.
