Bezos will soon marry Lauren Sánchez in Venice. Protesters say the city, already grappling with overtourism, is putting the wedding over their needs — which city officials and wedding organizers deny.

"If you can rent Venice for your wedding, you can pay more tax," activists said on the banner protesting Bezos before his wedding.

Greenpeace has joined the smattering of protests in Venice against the upcoming wedding of Amazon founder Jeff Bezos and Lauren Sanchez.
