This was a very nicely done tribute, but I am in shock that this was Dana's last day. We knew Dana (and Dick Brennan) were leaving the 6pm newscast, but she was supposed to remain with the station as a fill-in anchor and contributor. However, per an article in Newsday.com (paywalled), which cited a memo from GM Johnny Green, Dana thought about it and decided that today would be her last day. The Newsday.com article goes on to mention that several in the news industry believe this move is directly related to budget cuts at Paramount Global.
Regardless of the reason, this feels like a pretty abrupt ending for someone who devoted nearly 34 years of her life and career to this station. The entire process, starting with a leaked internal memo announcing that Dana and DIck would be "transitioning" off the 6pm newscast, seems like it was completely mishandled.
