"I must tell you that the courses that I took were outstanding," says Kent Moyer, the founder of the World Protection Group, which bills itself as an international security firm." Moyer said he still listens to audio of the courses he took every now and then.
Casey Hoban, a founder of Trimino, which makes protein-infused water, says in the video that Trump's business techniques were a major asset in his business dealings.
Michelle Gunn, introduced in the video as an entrepreneur and real estate investor, says "we never felt pressured to do anything we didn't want to do." Gunn raises the possibility that unhappy former Trump University students did not take sufficient action to apply what they learned in the real world.
The release of the video follows widespread media coverage of testimony made public on Tuesday that suggested Trump was personally involved in devising the marketing strategy for Trump University. The testimony is related to an ongoing lawsuit and was made public by a federal judge in response to a request from The Washington Post.
Trump was once a 93 percent owner of Trump University. Former students have alleged they were misled by the institution. Former employees have described it as a scam and provided documents showing that instructors were encouraged to aggressively push prospective customers toward the most expensive courses.
Trump has repudiated the allegations in the case.
Democratic front-runner Hillary Clinton seized on the Trump University revelations on Wednesday, signaling she intends to press the issue as the general election phase of the campaign begins to unfold.
"His own employees testified that Trump U. — you can't make this up — that Trump U. was a fraudulent scheme where Donald Trump enriched himself at the expense of hard-working people," Clinton said while campaigning in Newark. "This is just more evidence that Donald Trump himself is a fraud."
