From different stories I have read on president trump, and other various anecdotal tales, I really do think That at a point sometime within the last ten years, trump got saved.
There is too much a difference between the Trump of the 1990’s in New York (I lived and worked in Brooklyn and the news was all about Trump) and the Trump of the 2010’s.
Only God knows a mans heart, but there was a change and there was a new direction sometime around 2007-2008.
Possibly and only God knows... but there are signs that indicate the reality and veracity of an individual's conversion. https://www.whatchristianswanttoknow.com/7-signs-of-a-true-conversion/
