Trump is a bit naive here. There is no such thing as government as usual, but democrats taking over government while masquerading as legitimate authority. He would be giving an iphone backdoor for democrats to spy and harass his family and friends that supported him.
I’m with Apple on this one. No American citizen or company should feel any obligation to help an organization as corrupt as the DOJ/FBI. This is especially true in a case involving a terrorist attack carried out by a foreign national working on A FREAKING MILITARY BASE here in the U.S.
