In Daniel 7 & 8 the beast with ten horns is provided a mouth that speaks great things.
This mouth that speaks great things casts some of the stars of heaven to the ground and stamps all over them (Daniel 9:10).
He is also described in Daniel 8:12 casting truth to the ground.
With the understanding that the Lords angels provide mankind with illumination and truth, we can then assess the stars of heaven that are cast to the ground being the illumination Gods angels provide mankind.
He has a massive ego (Daniel 8:11), which makes him see himself as God.
While the little horns mouth is speking his great things and denying truth, he also causes craft to prosper (Daniel 8:24-25).
Now let's look at Trump.
He constantly speaks how great things are going to be.
He is a pathological liar.
He has a massive ego.
His policies so far seem to have caused the stock market to sky rocket.
While these truths about Trump do not necessarilly mean Trump is the beasts mouth, he nevertheless does meet all the criteria I have posted so far.
Daniel 7:8 I considered the horns, and, behold, there came up among them another little horn, before whom there were three of the first horns plucked up by the roots: and, behold, in this horn were eyes like the eyes of man, and a mouth speaking great things.
20 And of the ten horns that were in his head, and of the other which came up, and before whom three fell; even of that horn that had eyes, and a mouth that spake very great things, whose look was more stout than his fellows.
25 And he shall speak great words against the most High, and shall wear out the saints of the most High, and think to change times and laws: and they shall be given into his hand until a time and times and the dividing of time.
Daniel 8:10 And it waxed great, even to the host of heaven; and it cast down some of the host and of the stars to the ground, and stamped upon them.
11 Yea, he magnified himself even to the prince of the host, and by him the daily sacrifice was taken away, and the place of the sanctuary was cast down.
12 And an host was given him against the daily sacrifice by reason of transgression, and it cast down the truth to the ground; and it practised, and prospered.
24 And his power shall be mighty, but not by his own power: and he shall destroy wonderfully, and shall prosper, and practise, and shall destroy the mighty and the holy people.
25 And through his policy also he shall cause craft to prosper in his hand; and he shall magnify himself in his heart, and by peace shall destroy many: he shall also stand up against the Prince of princes; but he shall be broken without hand.
