Kamala Harris is starting to respond to calls by media outlets and voters to share a detailed economic policy plan ahead of November, including making billionaires “pay their fair share.” Harris delivered a speech to the Economic Club of Pittsburgh on Wednesday, along with the release of a policy book that lays out her strategy to lower costs and “create an opportunity economy” for the middle class. In Pittsburgh, Harris attempted the delicate balance of reaching out to undecided voters while also appealing to those already excited by her campaign as she replaced President Joe Biden as the Democratic nominee.
