Last year Bernie Sanders made free college tuition the centerpiece of his presidential campaign. Now, a candidate for Seattle mayor wants to make that idea hers.

Former U.S. Attorney Jenny Durkan is calling for "free college tuition for every graduate of Seattle public high schools.”

The proposal would offer two years of tuition to attend a public community or technical college in the state, building on current efforts in Seattle community colleges that now help students.

Durkan estimates the new plan would expand those tuition programs to help to around 1,500 students per year, and would also now cover all additional fees.

"As we get ready to go back to school I want every kid to know that if they do their part we promise we'll do our part," Durkan said.
