The Violence Against Women Act, which has been law since 1994 and a consistently easy bill to renew each year, was prevented from coming to a vote on the House floor at the end of the last session because some members of Congress were uncomfortable with additional language protecting Native Americans, LGBTQ people, and undocumented immigrants. I'll let you guess which party they were from. The bill died.
The bill does a lot of important stuff. Learn about it. Then yell at your congresscritters. They'll be bringing it back up for a vote soon.
