Congressman Bill Foster (D-Ill.), a PhD-trained scientist, is planning to attend the March for Science in Washington on April 22.

WASHINGTON — Congress’s one PhD-trained scientist is planning to join the march on Washington on April 22 — “not as a Democratic member of Congress, but as a scientist.”

Thousands of scientists and science advocates are expected to participate in the March for Science, and Congressman Bill Foster of Illinois, a Democrat and physicist, will join them. He’s even planning to return three days early from a congressional recess to attend.
