Democrats are planning to grill Michael Cohen about Trump Organization money laundering

Michael Cohen's testimony has already set off bombshells, based on a prepared statement he will deliver to the House Oversight Committee, but Democrats plan to pursue another area that hasn't yet drawn as much attention.

The longtime Trump Organization lawyer will tell lawmakers the president knew about Roger Stone's contacts with WikiLeaks and spoke with his son about an infamous meeting with a Russian attorney promising dirt on Hillary Clinton, but NBC News reporter Heidi Przybyla said Democrats are also interested in Trump's shady business dealings.

"Beyond that, Democrats want a lot more, and they want to delve deep into this issue of money laundering, not just with Russia but other potential foreign countries," Przybyla told MSNBC's "Morning Joe."

"There was a story that maybe didn't get a lot of attention last year in February," she continued, "about a Trump Tower last year in Panama, where the South Americans were essentially trying to kick out Trump business officials. They saw them going into a room with documents, and they heard a shredder going."

"Why is that important?" Przybyla added. "Democrats are going to dig into this whole notion how the Trump Organization operates with these shell companies, which are supposed to be investments, and a lot of these individuals and foreign countries think are going to be investment but actually turn out to be shell companies potentially used for money laundering."
