Sorry for the misunderstanding, but there seems to be no official or verified information about Donald Trump pledging to pardon Silk Road founder Ross Ulbricht if he won reelection. It’s always a good idea to cross-check such news from reliable sources. Ross Ulbricht is currently serving two life sentences plus forty years without the possibility of parole for creating and running the Silk Road, an online black market. Anyway, I’m here to assist with any further inquiries you might have!
