Robin Roberts Thanks Michelle Obama, 'Today' Show Staff for Support

UP: Robin Roberts

The "Good Morning America" anchor lands a huge scoop with President Obama's same-sex-marriage interview, adding to GMA's recent momentum in its ratings battle with NBC's "Today."

The day after Robin Roberts revealed she has been battling a blood and bone marrow disease, the Good Morning America anchor spent time thanking well-wishers for an outpouring of support.

Roberts, who told viewers Monday she had been diagnosed with myelodysplastic syndrome (MDS), thanked First Lady Michelle Obama, who had earlier tweeted, "Barack and I have you in our prayers. We believe in you and thank you for bringing awareness and hope to others. –mo”

On Tuesday morning, the official Twitter account of NBC’s Today show tweeted “Sending our thoughts and best wishes to @RobinRoberts!”

Robins tweeted that she had received phone calls of support from a number of Today staff, which her show has been competing with in a well-publicized ratings battle. On Monday, Roberts revealed that she learned about her diagnosis in April, the same day her ABC show beat Today in the ratings for the first time in sixteen years.

Through dozens of tweets, Roberts has also acknowledged Twitter followers who have shared their own experiences with MDS. One woman tweeted that her husband had beaten the disease in the 1980s.

“Thank you for sharing about your husband...very helpful to hear success stories. Appreciate the prayers too,” Roberts tweeted in response.

MDS, which was once called pre-leukemia, is sometimes caused through cancer treatment. Roberts previously had fought breast cancer in 2008, which she has spoken about in multiple interviews.
