I think he's pretty clearly ESTP and he's basically the posterboy for the MBTI 16 "ESTP" ie Se-Ti at that.
The argument for him being a Te lead is defeated by the simple fact that Trump doesn't care about what makes external logical sense, he doesn't include other people in his decisions, he doesn't look outwards towards what is going to be accepted as logical - Trump looks within Trump for his decisions - meaning, his decision making process is introverted, and he looks at what makes the most sense to him - though, he does have a very solid understanding of what will have the most impact with regards to the wider social spectrum of Feeling so it's not like his F is non-existent - and, it's clearly extraverted.
That said though, does Trump actually make decisions in accordance with social values? Nope. Like I said. Trump looks to Trump for his decisions.
Ergo, his introverted Thinking is preferred over his extraverted Feeling.
With regards to S/N - there's not a whole lot to talk about here, N is obviously his biggest flaw - he can't see what's coming, he simply can not connect the dots and project his imagination into the future - he is the posterboy for the silly MBTI "Se" stereotypes whereby someone is so wrapped up in the present moment they can't see anything else.
Trump gathers too much information than he knows what to do with, hence why so many things he says are untrue or have a very very tiny amount of truth in them - so he's gathering real-world facts, but he's not making any sense of them at all, he's not comprehending and understanding the information.
So due to the above, I place him as Se over Si - Si types, due to introversion, mull over known information *more than* people preferring to take in more and more and more information (Se/Ne).
So for the reasons above, Trump is a stock-standard MBTI 16 types SeTi type, imo.
His information gathering process is Sensation, and it is extraverted - this is cross-checked with an inferior intuition that is found within him failing to project anything into the future, he can't do anything non-tangible, there's a huge disconnect between Se and Ni with this guy.
I agree his Te is screwed...hence
The unhealthiest types of ESTJs tend to operate with a warped or highly imbalanced Extraverted Thinking function. They tend to appear as dominating, aggressive, controlling, and confrontational. They like to be in charge, but when in charge they become the strictest micro-managers, seeing their way as the only “right†way and ignoring other alternatives or perspectives. They see things in extremely black and white contexts, jump to conclusions quickly, and are insensitive towards others. They may pride themselves on “saying it like it is†and may feel that this is simply honesty and therefore a trait to be admired. However, there’s a certain pride in their “no-holds barred†criticism, and they can walk all over other people and their feelings without care or concern.

Destructive ESTJs are dictatorial, aggressive, and controlling. They believe that they know what’s best for everyone, and that their way is the only way. They suppress their moral compass and disregard the feelings and values of other people in exchange for their own rigid views. They push forward to achieve their goals, but instead of taking time to reflect on their decisions, they steamroll over everyone in their path in order to accomplish tasks without considering alternate viewpoints or the moral implications of their actions. They may be loyal to a corrupt system or authority and suppress anyone who stands against that authority or questions it. They trust their own personal experience and disregard other people’s experience. They scoff at the emotions and values of others while they allow themselves to have their own temper tantrums and emotional overreactions
