I do not think there is anyone in the administration honest enough to get substantive information.
Like I've said before, why treat Trump with kid gloves to maintain access? All the access is going to be lies anyway. Why bother? Just get your facts elsewhere and report the damn news. "Banned from the White House" just means your sources are going to be far more truthful.
If the truth pisses off Trump and his toadies, that means you are doing your job as a reporter.
