WASHINGTON -- Senate Democratic Leader Harry Reid called Donald Trump "a human leech" in a floor speech Thursday attacking the Republican presidential nominee's business record, including his history in Atlantic City.

Reid (D-Nev.) also called Trump a "notorious con man," a "spoiled brat," and someone who "rips people off" and got richer "swindling working men and women" in his address.

"Trump is a human leech who will bleed the country and sit at his golf resort laughing at the money he has made, even though working people have been hurt and ruined," Reid said. "How could he understand working people, because he's only out for Donald Trump."

Reid's comments were made as polls indicated Trump closing the gap with Democratic nominee Hillary Clinton and had pulled ahead in some states, including Nevada, albeit with the surveys' margins of error.

Trump campaign spokeswoman Hope Hicks did not respond to a request for comment.

Reid, former chair of the Nevada Gaming Commission, said Trump has a gambling license in that state, but based on his record in Atlantic City, he couldn't get one now.

Trump's Atlantic City casino companies went bankrupt five times over 25 years and several of his contractors never got paid.

"I understand what took place in Atlantic City," Reid said. "If he applied for a license after what he has done in Atlantic City and what he has done since, he couldn't get a gaming license in Nevada."

Reid rejected Trump's assertions that his plans would help the middle class.

"Donald Trump is only trying to help one person, Donald Trump," Reid said. "He is a spoiled brat, raised in plenty, who inherited a fortune and used his money to make more money. And he did a lot of it by swindling working men and women. Why would he change as president? The answer is simple: Trump won't change. He is asking us to let him get rich scamming America."
