I do not know, did he say it? Because people like you always say that Trump said something, but never provided links, videos, or pictures of him saying it.
Besides, the lawyer is just trying to save time. There is no law that protects the identity of a whistleblower.
Plus, people like you like to turn the sound out of what Trump says. Trump could say, "I'm thinking about getting a dog." And you'll hop here or wherever and say, "Tump said he wants a dog, why can not you see that we have a racist president calling black people dogs and wanting to enslave black people again."
