(AP) — Television icon Barbara Walters has returned to her Massachusetts roots to talk about her long career at Harvard University's Kennedy School of Government.

The former news anchor and co-host is known for her interviews with international newsmakers such as Hillary Clinton. She grew up in the Boston area and New York City, where her father owned nightclubs.

She said Tuesday evening a journalist's most important asset is curiosity.

The 85-year-old Walters stepped down from daily television on her ABC show "The View" in May but still does special projects for the network.

Walters was asked about Clinton, who appeared on her farewell "View" episode. She says Clinton "would make a very good leader as president" but she "wouldn't bet 100 percent" that Clinton will decide to run.

(AP) — It's almost enough to make their fans nostalgic: Stephen Colbert and his "Papa Bear," Bill O'Reilly, going after each other again for probably one of the last times.

Colbert is mocking the Fox News Channel host's proposal that a 25,000-member mercenary force be armed and trained to fight the Islamic state. Colbert countered with his own "army of expert double Ninja super soldiers with laser nunchucks," imagined when he was in the fourth grade.

Colbert essentially modeled the cable news opinion host character he's been playing on Comedy Central's "The Colbert Report" after the Fox News ratings king. But as he prepares to replace David Letterman on CBS next year, Colbert is shutting down his show and the character itself at the end of the year.

Colbert's comic takedown of the plan drew O'Reilly's ire, and Colbert on Wednesday night subsequently called O'Reilly an "egomaniac," adding an expletive.

Earlier in the week, O'Reilly said that Colbert "and others of his ilk have no bleepin' clue how to fight the jihad. They don't know anything."

But even though he's "completely vacant," that doesn't stop Colbert from "mocking ideas that might have some value," O'Reilly said on his show Monday.

Colbert struck back on his show Wednesday.

"It hurts me to know I hurt the man I admire most," he said. "Just as Bill would be hurt to know he hurt the man he admires most — himself."

Colbert played news clips of other Fox News personalities dismissing O'Reilly's idea.

"I wasn't mocking your plan," he said. "I'm the only one who likes it."
