Washington, August 9 (RHC)-- U.S. Democratic Senator Elizabeth Warren has denounced Republican presidential nominee Donald Trump’s economic vision he outlined in a speech to the Detroit Economic Club.

In a series of tweets on Monday, Warren, a Democratic senator from Massachusetts and former Harvard Law School professor, said the billionaire businessman’s economic plan “was written by rich corporate insider advisers to make the economy even greater for rich corporate insiders.”

Earlier in the day, Trump described his policy to revitalize America’s economy, an attempt to refocus his campaign after a series of missteps that cost him dearly in the race against Democratic presidential nominee Hillary Clinton.

Warren blasted Trump and his economic vision for the United States, accusing him of tipping the scales for the wealthy Americans. The U.S. senator said: “Cheating customers and gaming the system might be your business, but it’s not the way America is going to do business.”

The Massachusetts senator has recently intensified her attacks against Trump, calling him “a lousy businessman” and selfish human being. She has also joined a group of Democrats demanding Trump publicly release his tax returns, implying that the New York real estate mogul is lying about his true business value.

Last week, Trump announced his economic team, which includes 13 men, no women, several billionaires, an Oklahoma oil baron and one part-time professional poker player. Most notably, his team includes John Paulson, who made billions by betting against the housing market in the lead-up to the 2008 crash.

U.S. Senator Elizabeth Warren earlier denounced Donald Trump’s ethics, calling him “a small, insecure money-grubber.”
