In the letter, Schultz asked baristas at Washington, D.C.-area Starbucks to write “Come Together” on coffee cups for the rest of the week.

“In the spirit of the Holiday season and the Starbucks tradition of bringing people together, we have a unique opportunity to unite and take action on an incredibly important topic,” Schultz wrote. “Rather than be bystanders, we have an opportunity—and I believe a responsibility—to use our company’s scale for good by sending a respectful and optimistic message to our elected officials to come together and reach common ground on this important issue.”
