A new report says last week’s firing of Jamie Horowitz from the top job at NBC News’ “Today” show came after Horowitz proposed sweeping changes to the show. He was fired barely three months into his tenure, which was an observation period before his scheduled official start Dec. 1.

The Hollywood Reporter’s Live Feed reports that his undoing came after he made a five-hour presentation in mid-November to NBC News President Deborah Turness that proposed sweeping changes that would have affected many of the show’s cast of characters.

Among Horowitz’s proposed changes: “Today” lead co-anchor Savannah Guthrie would be dropped, and Natalie Morales would be demoted, the story reports.

In addition, THR reports, his plan called for 10 a.m. co-anchor Hoda Kotb to move to the show’s earlier hours, and longtime weatherman Al Roker to be moved off that beat. Meanwhile, Josh Elliott was targeted by Horowitz for a much bigger role at the show.

Instead, Horowitz was summarily fired.
