Robin Roberts returns to “Good Morning America”

NEW YORK (AP) -- Five months after undergoing a bone marrow transplant, Robin Roberts is back on television in the morning.

Roberts said Wednesday she'd been waiting 174 days "to say this, good morning America."

The morning-show host is recovering from MDS, a blood and bone marrow disease. She looked thin with close-cropped hair but was smiling broadly, back at work on "Good Morning America" at ABC's studio in New York City.

Roberts was welcomed back in a taped message from President Barack Obama and his wife, Michelle, former ESPN colleagues and Magic Johnson.
