Hillary Clinton is now taking aim at Donald Trump's business acumen.

Speaking at a large union convention today, the Democratic presidential front-runner ripped into her likely opponent’s business record, warning that he "could bankrupt America like he’s bankrupted his companies.”

"Trump economics is a recipe for lower wages, fewer jobs, more debt,” Clinton told the SEIU members at the Cobo Center in downtown Detroit. "He could bankrupt America like he’s bankrupted his companies.”

"I mean ask yourself, how could anybody lose money running a casino, really?” she added.

Over the past few weeks, Clinton has focused most of her attacks on Trump’s foreign policy positions, casting him as a “loose cannon” who is dangerous to the security of the country.

The former secretary of state began going after Trump’s business record on Sunday in an interview on NBC’s “Meet the Press” in which she called on the real estate mogul turned Republican presidential candidate to release his tax returns and suggested they may show he is less successful than he appears.

The line of attack is one that Trump has seen before. His former Republican opponent Marco Rubio frequently called him out on this issue.

Today Clinton also criticized Trump’s personality.

"We need a president who will use the bully pulpit to stand up for working families,” she said. “But the last thing we need is a bully in the pulpit.”

Trump's companies, including the Trump Taj Mahal, have filed for bankruptcy four times.

Trump has said he never declared personal bankruptcy and used the laws to his advantage as a businessman.
