I'm almost certain you don't say this in good faith, but let's spend a little time in google anyway, and ignore that his platform in 2016 has had an incredible amount of influence on the platform of the candidates running for 2020. I'll pick out some stuff that stands out to me, and provide sources for your own perusal.
Here are some amendments he's added to legislation that was passed:
- in 1995, requiring corporations to notify victims of fraud and other white collar crime that they are eligible for restitution
- in 2001, securing an additional $100 million in funding for federally qualified community health centers
- in 2001, prohibiting importing of goods made by forced or indentured child labor
- in 2004, securing $22 million increase for low-income home energy assistance and weatherization programs
- in 2007, requiring at least 30% of hot water in federal buildings be provided by solar water heaters
- in 2012, requiring public availability of the database of senior Department officials seeking employment with defense contractors.
It's admittedly more difficult to find legislation he's outright authored and gotten passed (it turns out there are just three such bills), but in 2013 he introduced several bills to provide better care for veterans and increase the rates of their disability compensation, among other things, which were eventually passed with, gasp, bipartisan support.
He
also spent time campaigning across the country to defend the ACA but I assume you'll have objections to that being an accomplishment. (Sorry about the half assed citation on this one, there are a ton of articles that come up when you search for anything healthcare related and Bernie Sanders)
This blog post has links to the mentioned amendments and legislation if you dig that kind of thing.
I'm pretty sure he has some noteworthy accomplishments as mayor as well, but a lot of the legalese I've encountered since putting this together this has left my brain fried, and it's a weekend, so I'm done now.
You can also play with the filters
here, to see more amendments and such, as well as legislation he introduced but didn't become law, if that tickles your fancy.
