Hands Off! protests
Sat, Apr 5 — throughout the US

These protests are "a nationwide mobilization to stop the most brazen power grab in modern history." The messaging can be about anything involved in the Trump/Musk power grab, i.e., the events won't be single-issue.
There will be an organizing call on Tues, Apr 1, 8–9 Eastern.
They have signs you can print, including templates so you can make your own sign. After "Hands Off!" you can print "Medicare," "Libraries," "Cancer Research," and so on.
The protests will be Sat, Apr 5, generally around noon. They're locally organized. Sign up to host an event, or find one that's being organized, at handsoff2025.com
