TLDR: Maryland Democrat Rep. Dutch Ruppersberger, founder and co-chair of the House Municipal Finance Caucus, has announced his retirement at the end of his term. Ruppersberger, who has served on the Hill for 21 years, played a crucial role in advocating for the municipal bond industry and protecting the tax exemption for municipal securities. He also helped avert billions of dollars in infrastructure cuts in the Tax Cuts and Jobs Act of 2017. Ruppersberger’s retirement leaves a void in the bipartisan caucus, which has been instrumental in advancing public finance priorities in Congress. His replacement on the caucus has yet to be determined.
