WashPIRG and Public Citizen plan to deliver petitions to Starbucks headquarters Tuesday asking CEO Howard Schultz to institute a corporate policy against spending money in elections and to ask other CEOs to do the same.
Two years ago, Schultz asked other CEOs to stop making campaign donations because of gridlock in Washington, D.C.
Starbucks will have its annual shareholders meeting at 10 a.m. Wednesday at Seattle Center's Marion Oliver McCaw Hall.
Investors will vote on a shareholder proposal that would prohibit political spending.
Starbucks' board of directors recommends investors vote against the proposal, saying the company has a responsibility to advocate for public policies that support its business, employees and communities.
