Democratic presidential aspirant Bernie Sanders has not been shy in calling Donald Trump a pathological liar and a divisive demagogue. Now, the Vermont senator is taunting the Republican frontrunner for his crude views on climate change.

Speaking at a rally in New Hampshire, Sanders recalled a statement from Trump in which the business magnate argued that "the concept of global warming was created by and for the Chinese in order to make U.S. manufacturing non-competitive."

"What an insight," Sanders said via The Washington Post. "How brilliant can you be. The entire scientific community has concluded that climate change is real and causing major problems and Trump believes that it's a hoax created by the Chinese. Surprised it wasn't the Mexicans."

The 74-year old statesman has increasingly been criticizing Trump in his campaign speeches. He has also been reaching out to working-class Trump supporters, arguing he would better represent them on important issues such as income inequality and the threat of ISIS, per Latin Post.

Trump responded to the criticisms by calling the veteran politician a "wacko," among other things.

Meanwhile, Sanders was in New York on Tuesday to talk about his immediate plans if he becomes president. He said he will demobilize the country's largest banks and insurance companies within the first year of his administration.

Sanders would order his Secretary of the Treasury to come up with a list of financial institutions that were "too big to fail." He would then move to disband the companies, whose potential financial collapse would greatly stifle the country's economy, ABC News reported.

The presidential aspirant specifically mentioned several firms which he though exhibited reckless and monopolistic behavior on Wall Street. He referenced Citigroup, Bank of America and JP Morgan Chase.

Sanders said on CNN's "State of the Union" that wages for working-class Republicans are slowly decreasing while new wealth and income are going to the top one percent of the population.

"They can't afford to send their kids to college. They're seeing their jobs going to China," Sanders explained. "I think they want a president who has the courage to stand up to the billionaire class, to raise the minimum wage, to make public colleges and universities tuition-free."

He asserted that the next president should suppress a corrupt campaign finance system, where millionaires and billionaires impulsively spend large sums of money to buy elections.

"The American people want change," Sanders firmly declared. "I believe that I'm a vehicle of change, being prepared to stand up to the wealthy and the powerful and create an economy that works for all Americans."
