I think Trump’s defense of Farrakhan is in the spirit of “I disapprove of what you say, but I will defend to the death your right to say it.” I thought the person who originally said this was Patrick Henry, but a quick search yields several other sources. In any case, whether or not Patrick Henry was the originator of this phrase, Trump’s position certainly is in keeping with the founding fathers’ philosophy.
As far as I know, Trump said nothing about Farrakhan. That’s just the fake news saying Farrakhan is far right and lumping him into what Trump is talking about. He mentioned James Wood, Diamond and Silk and Paul Watson. That is all.
