A March for Science will be held Saturday in Washington, D.C., and hundreds of other cities in the U.S. Organizers say the march is a non-partisan celebration of science. It's meant to both encourage political leaders to fund science and rely on scientific evidence when making policy decisions. Critics worry the march will turn into an anti-Trump rally and paint scientists as just another interest group.
