Donald Trump's businesses aren't good at paying their bills

"I will be the greatest jobs-producing president that God ever created," Donald Trump said in a campaign video.

"I feel badly for everybody. What am I going to do? I'm in business," Trump told a crowd in Albuquerque.

"I don't settle lawsuits, very rare, because once you settle lawsuits, everybody sues you. Very simple. It's like business. I teach it," Trump said during a press conference.

Donald Trump frequently touts his business experience on the campaign trail. But now that business background is getting him some bad press.

See Trump through the years:

USA Today recently published a story about 3,500 lawsuits filed against Trump and his businesses in the past 30 years.

The paper says many of those lawsuits were over unpaid bills and filed by average Americans who completed work for Trump or one of his companies but didn't get paid in full. When asked, Trump didn't exactly shy away from the issue.

Trump told USA Today: "Let's say that they do a job that's not good, or a job that they didn't finish, or a job that was way late. I'll deduct from their contract, absolutely."

Trump made similar comments to The Wall Street Journal. He said, "I love to hold back and negotiate when people don't do good work."

In some cases, even Trump's own attorneys turned around and filed suits against him for not paying his bills.

Likely thanks to Trump's wealth, many of these lawsuits have dragged on for years, leaving some plaintiffs feeling that their only choice was to settle for less than they were owed.
