DENVER (AP) — Republican presidential candidate Rand Paul courted donors from the new marijuana industry Tuesday, making the Kentucky senator the first major-party presidential candidate to publicly seek support from the legal weed business. Paul’s fundraiser at the Cannabis Business Summit — tickets started at $2,700, the maximum donation allowed for the primary contest — came as the marijuana industry approached its first presidential campaign as a legal enterprise. The candidate entered the closed-door fundraiser through a private hallway, instead of visiting the convention floor or meeting pot business owners who weren’t donating to him. But many of the 40 or so people who attended the fundraiser called his appearance at the summit a milestone.
