On February 21, 2018, Q made a post which included a bracket and inside was 58 white spaces.
On February 22, 2018, a day after Q’s post, Trump sends a tweet out which contained noticeable portion of whitespaces, which using the same tools above, matches exactly 58 whitespaces as well.
What many people don’t understand, or don’t want to understand, is that Wayne, Chris and the folks who work so hard at the @NRA are Great People and Great American Patriots. They love our Country and will do the right thing. MAKE AMERICA GREAT AGAIN!

Wikipedia defines a whitespace as the following:
[ ] = 1 whitespace
In computer programming, white space is any character or series of characters that represent horizontal or vertical space in typography. When rendered, a whitespace character does not correspond to a visible mark, but typically does occupy an area on a page.
[ ] = 2 whitespaces
[ ] = 3 whitespaces, etc.
