Republican presidential candidate Donald Trump's business seminar programme created a class to teach students how to cash in on US mortgage foreclosures during the housing crisis.
Trump University promised in 2009 that its Fast Track to Foreclosure Investing would teach students how to take advantage of the crisis, according to university documents unsealed last week in a lawsuit against the now-defunct programme.
The release will likely stoke criticism from the campaign of Democratic front-runner Hillary Clinton, who last week accused her likely rival in this year's presidential election of having cheered on the 2008 housing crash as an investment opportunity.
A spokeswoman for Trump's campaign did not immediately respond to a request for comment, although Trump reacted to Clinton's criticism last week, saying: "What am I going to do? I'm in business".
A Trump University advertisement released in the case said one of its free investor workshops would explain how to "Cash in on one of the greatest property liquidations in history!"
