Robelot will be replaced for a month by Thalia Assuras, who currently delivers the news on CBS’s morning show. CBS announced last month that former “Today” host Bryant Gumbel will begin at “This Morning” in November. While CBS said it would launch a search for a Gumbel co-host, Robelot hasn’t been mentioned as a possibility. Her current co-host, Mark McEwen, will stay on with Gumbel to deliver weather and entertainment reports.
