Yes!
RPOTUS know his building materials!
I’ll never forget waiting it out, in a shopping center parking lot, in 100ยบ heat! ... listening to Rush’s interview with Donald Trump ... in 2014.
He talked about ChyNAH’s glass that was being imported, for US construction ... and, it was faulty (of course).
I came home and told hubby ... Donald Trump needs to run for President .... he’d be a GREAT President.
