Trump is famous for requiring his employees to sign nondisclosure agreements. Apparently also when his lawsuits are settled, there's a no-publicity clause in the agreement. So I posed a
question on this Post piece:
could Trump issue an executive order requiring all Presidential
appointees to sign a nondisclosure agreement modeled after the ones he
requires employees of his businesses? Don't know the answer.
I do know that the Supreme Court back in the 70's limited the right of the executive branch to restrict employees' contact with Congress.
