I am unable to copy the link as something with the formatting has gone wrong.
However, a quick Google suggests this to me.
Trump said it was going to rain, but in the end it didn't. His assumption is that God stopped the rain ruining his inauguration.
Some journalists say, however, that it DID rain during his inauguration.
So yes, there seems to be a discrepancy between what the weather did, and what Trump said it did.
