WATCH: Lawrence O'Donnell Finds Out Trump Once Sold Urine Tests

Donald Trump and his businesses took a big hit yesterday when he was fined $354 million and barred from doing business in New York. 

On Friday night, Alex Wagner hosted a discussion about Trump's issues with fellow hosts Lawrence O'Donnell and Rachel Maddow. And during a discussion of Trump's former businesses, the fact that he once sold urine tests came up, shocking Lawrence O'Donnell. 

Prior to speaking with O'Donnell and Maddow, Wagner discussed several of Trump's failed business ventures, remarking, "Trump stuck his name on everything from to golf courses and apartments, to vodka and steaks. There was even a Trump urine test because why not? If Trump was involved, it was good business – even if it was a urine test."

Upon joining the segment, O'Donnell joked, "First of all, on your trip down Trump memory lane, I thought that I had nothing to learn. Then came, I learned tonight, about the Trump urine tests… I had no idea that he was that interested in–."

The MSNBC host continued, "I know there are people in the audience who are still processing that and I wanted to help them with it and move on to this."
