Clinton discussed a plan to take on risk-taking in finance that would lead to the dismantling of too-big-to-fail banks.

“I have a plan to build on the progress we’ve made under President Obama and do just that,” Clinton said in a statement. “We can’t go back to the days when Wall Street could write its own rules.”

The proposal would make it so that there’s a fee instituted on firms that, she said, “are too large and too risky to manage.” Clinton would require that such institutions reorganize or downsize, according to CNBC.

This comes just days before the Democrats are slated to meet for their first debate of the political cycle.

For other Clinton news, she recently spoke out against U.S. current gun control laws and the NRA.
