Last week, scientist Neil deGrasse Tyson issued a stern warning to President Trump: don't mess with the science community.
On Late Night with Stephen Colbert, Tyson said "hold me back!" when warning what would happen if the Trump administration took any sort of anti-science actions.
Mere days after this warning, the Trump White House released their proposed budget.
This budget alarmed many. Its cuts were seen as deeply problematic. It also alarmed Tyson.
Tyson took to his Twitter and unleashed a torrent of critical tweets. He held no punches. The retweets and support were magnanimous.
