social media in key swing states around the country. we'll all take a look. >> the one thing kamala harris has always been, fearless. as a prosecutor, she put murderers and abusers behind bars. as california's attorney general, she went after the big banks and won $20 billion for homeowners. as vice president, she took on the big drug companies to cap the cost of insulin for seniors. because kamala harris has always known who she represents. >> this campaign is about who we fight for. we believe in a future where every person has the opportunity, not just to get by, but to get ahead. where every senior can retire with dignity. but donald trump wants to take our country backward. to give tax breaks to billionaires and big corporations and end the affordable care act. but we are not going back. >> i'm kamala harris, and i approve this message. >> it's a $50 million ad buy.
