EMILY STEEL

After 45 years on the public broadcaster PBS, Big Bird, Elmo and the rest of the “Sesame Street” crew are settling into a renovated set as well as a new television home on the premium cable network HBO.

The Fox News host Bill O’Reilly on Monday stepped up his defense against reports that he embellished stories about his war reporting earlier in his career, while some former colleagues continued to say he had exaggerated his experiences.

Brian Williams, the embattled NBC news anchor whose credibility plummeted after he acknowledged exaggerating his role in a helicopter incident in Iraq, was suspended for six months without pay, the network said Tuesday night.
