About 30 "Stand Up For Science" rallies happened on Friday worldwide to protest the Trump administration's research funding cuts and science policy changes. Well, scientists clearly showed up and showed out with some very clever protest signs.

Hundreds of protestors — many of them veterans — gathered Friday afternoon outside the Ohio Statehouse to protest the Trump administration's plans to fire Department of Veterans Affairs workers and other controversial policies.

In the crowd were many veterans, including some who served during the Vietnam War. There was even a World War II veteran.

Washington, D.C.'s protest is to occur on the National Mall on Friday, with similar movements scheduled at all 50 state capitols.
