During his victory speech after the Michigan and Mississippi primaries, Republican presidential front-runner Donald Trump challenged the press to check the records on his past business ventures. Comedy Central's "The Daily Show" happily obliged.

"You just have to go check the records, folks," Trump said in an unusual press conference in which he displayed many of his branded products, including Trump Wine, Trump Water and Trump Steaks. "In fact, the press: I'm asking you, please check."

On "The Daily Show" Wednesday, host Trevor Noah put correspondent Jordan Klepper on the case. According to Klepper's fact checking, just about every claim Trump made about his products Tuesday was false.

Klepper started with Trump Winery. The billionaire real estate mogul claimed during his speech that he owned the company outright. However, Klepper pointed to the company's website, which claimed that Donald Trump has no connection to its business. Indeed, while Trump Winery is run by Donald Trump's son Eric Trump (a detail "The Daily Show" left out), the website for the winery clearly states that the company "is not owned, managed or affiliated with Donald J. Trump, The Trump Organization or any of their affiliates."

Klepper next targeted Trump Steaks. Trump displayed a pile of what he insinuated were Trump Steaks, which were sold at The Sharper Image retail stores in 2007. Trump even offered to sell them to the crowd for $50 apiece. Klepper reiterated the widely reported fact that Trump Steaks were discontinued after disappointingly low sales.

Many journalists and Twitter users were quick to point out Tuesday that the steaks Trump displayed on stage appeared to be Bush Brothers steaks, not Trump's.

Finally, Klepper took on Trump magazine. Trump had held up what he implied was a recent issue of Trump Magazine in his press conference. Klepper explained that while there was a Trump Magazine from 2007 to 2009, the magazine Trump held up Tuesday was called "The Jewel of Palm Beach," which Klepper referred to as "basically the brochure for Trump's hotels." The website for the magazine calls the annual glossy "the exclusive publication of Donald J. Trump's spectacular Mar-a-Lago Club" and explains it is only "distributed at Mar-a-Lago and Trump International Golf Club in the Palm Beaches."

Trump's unorthodox press conference was a response to a speech from 2012 Republican nominee Mitt Romney on March 3 in Salt Lake City, Utah, in which Romney criticized Trump's past business ventures.

“He inherited his business. He didn't create it,” Romney said. “And what ever happened to Trump Airlines? How about Trump University? And then there's Trump Magazine and Trump Vodka and Trump Steaks and Trump Mortgage? A business genius he is not.” He continued: "His is not the temperament of a stable, thoughtful leader," Romney said, calling Trump "a phony" who is "playing the American public for suckers."

Despite Romney's efforts, Trump extended his lead in the delegate count with his wins in Michigan and Mississippi and Hawaii. Trump has now secured 458 delegates. Texas Sen. Ted Cruz is a distant second with 359 delegates, followed by Florida Sen. Marco Rubio with 151 delegates and Ohio Gov. John Kasich with 54 delegates. The candidates square off in a debate Thursday night in Miami ahead of the all-important Florida primary Tuesday.
