— -- 1. Trump Calls Out Protester Wearing a Turban: 'He Wasn't Wearing One of Those Hats, Was He?'

A protester wearing a turban interrupted Republican presidential candidate Donald Trump during a rare Sunday appearance and the GOP front-runner called out the man as he was escorted away by security.

Trump had been talking about the Sept. 11 terror attacks and the San Bernardino shooting during his campaign event in Muscatine, Iowa.

The man in a bright red turban stood up and revealed a sign reading "Stop Hate."

Trump stopped his remarks as the crowd chanted "USA, USA, USA." When they quieted down, Trump pointed into the audience.

Referring to the protester while appearing to also point to a supporter in the audience, Trump said, "He wasn't wearing one of those hats was he? And he never will, and that's OK because we got to do something folks because it's not working."

2. Two Feet of Snow Not Stopping Sentinels at Tomb of Unknowns

Almost two feet of snow at the Tomb of the Unknowns at Arlington National Cemetery did not stopped the small group of soldiers who continually stand guard at the hallowed memorial.

Since April 6, 1948, Tomb Sentinels from the Army 3rd Infantry Regiment's "The Old Guard" have guarded the Tomb for 24 hours a day, 365 days a year regardless of the weather. And that includes hurricanes and blizzards.

"They told me this morning that the snow on the plaza is up to their knees and the wind is blowing sideways," Maj. Russell Fox, a spokesman for the Old Guard, said on Saturday, as the snowstorm raged. "They’re working to maintain a small pathway so they can continue to perform their duty."

3. Woman Confronts Hillary Clinton About Her Health

Hillary Clinton laughed off a question about her health Saturday from a woman who said she'd heard on Fox News that the Democratic presidential candidate "was really not equipped to be in the White House" because she was ill.

The question drew laughter from the crowd of roughly 450 at a campaign event in Clinton, Iowa, and an eye roll from Clinton.

"Oh my. Well, you know, they say nearly anything about me. I've got to tell you," Clinton, replied with a smile, referring to Fox News. "There are several themes they keep beating the drums on."

Clinton, 68, then addressed her health.

"I'll match my endurance against anybody," she said to loud applause. "And last spring, my doctor put out a letter and you know, said what great health."

4. Oscars Producer Says Chris Rock Is Rewriting Opening Monologue Amid Diversity Controversy

An Oscars producer said host Chris Rock completed his opening monologue for the awards show a week ago, but now he's scrapped it and is re-writing it after the controversy surrounding this year's show.

Many stars have spoken out about the lack of diversity in Oscar nominees for the second year in a row, slamming the Academy for being too homogeneous. Will Smith and Jada Pinkett Smith said they would not attend this year's show, as did director Spike Lee.

Oscars producer Reginald Hudlin told Entertainment Tonight: "Chris is hard at work. He and his writing staff locked themselves in a room. As things got a little provocative and exciting, he said, 'I'm throwing out the show I wrote and writing a new show.'

"Chris is that thorough," Hudlin continued. "He's that brilliant, and I have 1000 percent confidence that he will deliver something that people will be talking about for weeks."

5. National Zoo's Giant Panda Tian Tian Is Really Enjoying the Snow

As a severe winter storm pummeled Washington, D.C., keeping most indoors, one of the city's beloved residents spent time playing outside and enjoying the snow.

The National Zoo posted video and photos Saturday of its giant panda Tian Tian, an adult male, rolling around in the fresh powder and making what looked to be snow angels.

The 264-pound panda -- whose name means "more and more" -- is also seen throwing snow, rolling down a snow-covered hill, appearing to be having the time of his life.
