To that end, Clinton says she supports a constitutional amendment barring it.
“We need to fix our dysfunctional political system and get unaccountable money out of it once and for all, even if that takes a constitutional amendment,” Clinton said at the first event of her 2016 presidential run, speaking to students and teachers at Kirkwood Community College in Monticello, Iowa.
Clinton has said similar things in the past--just not as strongly. In 2014, for instance, she said she would consider such a measure, MSNBC reported at the time.
Clinton also backed President Obama's call for free community college.
"I fully support President Obama's plan to make community college free," Clinton said.
The community-college roundtable discussion was the first of what Clinton's campaign has described as a series of smaller, more intimate events in Iowa, where the former secretary of State will listen to voters on an array of issues.
Sitting at the head of several folding tables, Clinton asked the small group of attendees about their experiences as students paying tuition and planning their lives, and as educators seeking to help students along the way.
After officially announcing her candidacy this week, Clinton traveled to Iowa in a van she dubbed "Scooby," making a surprise stop at Chipotle along the way. Her campaign has not yet publicly disclosed a full list of the events she'll attend while she's in the state.
