WASHINGTON (AP) – Once-confidential manuals for Donald Trump’s one-time real estate business show the business encouraged high-pressure sales tactics and recognized it faced legal risks.

A judge unsealed the documents earlier this week as part of a class action lawsuit filed by former students of Trump University, Trump’s real estate seminar company. The manuals call into question Trump’s portrayal of his one-time real estate seminar course as an uncontroversial operation focused on helping aspiring investors. The guides encourage aggressive sales tactics and also advise staff on how to deal with prosecutors investigating Trump’s business.

Trump University stopped operating in 2011. In addition to litigation brought by New York, the Republican attorney general in Texas also investigated Trump University, ultimately dropping the probe in exchange for its promise to cease operating in the state.
