CBS News is expanding its investigative reporting unit, the I-Unit, with the hiring of journalists Josh Boswell and Cho Park. The additions, confirmed by internal memos, signify a broader network strategy to increase exclusive, cross-platform investigative content. The I-Unit, led by editor in chief Bari Weiss and senior investigative editorial director Matthew Mosk, has recently added seven new staff members to bolster coverage of politics, health, and taxpayer accountability.
Why is CBS News expanding its investigative team?
The network aims to prioritize stories that cannot be found elsewhere, according to a memo sent to staff by Matthew Mosk. By recruiting journalists with backgrounds in high-profile investigative work, CBS News is positioning its I-Unit to compete more aggressively for original scoops across digital and social platforms. This push follows the March hiring of Daniel Gilbert, Gabe Kaminsky, Laura Geller, Jake Rosenwasser, and Callie Teitelbaum, who have since reported on issues ranging from California hospice fraud to military preparedness in Kuwait.

The I-Unit’s expansion mandate includes a specific focus on health and wellness, sports, and the potential waste of taxpayer dollars, according to the network’s March announcement.
Who are the new investigative hires?
Josh Boswell joins the network from the Daily Mail, where he served as chief investigative reporter. His portfolio includes reports on the authentication of Hunter Biden’s laptop and allegations involving Doug Emhoff, which a spokesperson for Emhoff denied to CNN. Boswell’s expertise also covers cold cases, such as the Black Dahlia and Zodiac murders, and reporting on unidentified aerial phenomena. He is set to begin his role in Los Angeles on June 22.
Cho Park joins the team from ABC News, where she spent over a decade producing investigative content, including segments for Nightline. Her previous work highlights include covering racial discrimination allegations within the NFL’s concussion settlement program and sexual abuse investigations at major institutions. Park has already started in New York as a coordinating producer, with a focus on expanding the investigative unit’s digital and social reach.
How does this shift reflect current media trends?
The move by CBS News reflects a wider industry pivot toward “platform-agnostic” investigative journalism. By hiring producers like Park specifically to spearhead digital and social growth, the network is responding to a shift in how audiences consume long-form investigations. While traditional broadcast networks historically relied on evening news slots, the current strategy emphasizes the importance of social engagement to maintain relevance for in-depth reporting.

To follow the latest investigative findings from the I-Unit, viewers can monitor the network’s official digital investigative hub, which now features a wider array of multimedia reports than traditional broadcast segments allowed.
