Hillary Clinton is blasting Donald Trump's boastful plan to deport some 11 million undocumented immigrants as "really bad economics."

In a speech centered on the economy recently delivered to supporters in the swing state of Ohio, the presumptive Democratic nominee added, "Kicking out 11 million immigrants would cost hundreds of billions of dollars, and it would shrink our economy significantly. Some economists actually argue that just this policy alone would send us into a Trump recession."

Research Finds Trump Plan Would Weaken Economy 

Clinton's fiery words are bolstered by a recent Moody Analytics analysis in which researchers concluded a Trump presidency would "significantly" weaken the economy, driving the U.S. into a "lengthy" recession with nearly 3.5 million job losses and a 7 percent unemployment rate.

The chief economist on the analysis, Mark Zandi, is a former John McCain adviser and Clinton tried to strengthen her case against Trump by pointing out more than just democrats are clearly concerned about some of his proposed policies.

The former first lady and secretary of state also sounded the alarm bell when it comes to how Trump might handle such pressing issues as the national debt and making tax codes fairer for all Americans.

"A few weeks ago, I said his foreign policy proposals and reckless statements represent a danger to our national security," she said. "But you might think that because he has spent his life as a businessman he would be better prepared to handle the economy. Well, it turns out he's dangerous there, too. Just like he shouldn't have his finger on the button, he shouldn't have his hands on our economy."

Clinton also took the presumptive republican nominee to task over what she characterized as his willingness to gamble with the faith and credit of the U.S. by hinting he would allow the country to default on all its massive debt.

"That could cause an economic catastrophe, and it would break 225 years of ironclad trust that the American economy has with Americans and with the rest of the world," she added. "Alexander Hamilton would be rolling in his grave. You see, we pay our debts."

Clinton also highlighted the irony she sees in Trump boasting of his "America First" policy at a time when many of the billionaire businessman's signature merchandise is produced overseas.

"Interestingly, Trump's own products are made in a lot of countries that aren't named America: Trump Ties are made in China, Trump Suits in Mexico, Trump Furniture in Turkey, Trump Picture Frames in India, Trump Barware in Slovenia, and I could go on and on, but you get the idea," she said.

Clinton went on to blast Trump's claim that his business acumen make him a natural fit for the Oval Office and his ability to jump-start the overall economy would lead to him being revered as the "jobs president."

"He's written a lot of books about business. They all seem to end at Chapter 11," she said in a not so subtle dig at the numerous bankruptcies he has filed over the years. Go figure."

Trump Fires Back  

Trump immediately took to social media to refute many of Clinton's claims, including labeling Zandi an Obama adviser and Clinton donor.

He later ripped Clinton for what he called her role in the loss of more than a quarter of American manufacturing jobs over the last two decades stemming from President Clinton's enactment of the North American Free Trade Agreement.
