As Russian forces crossed the border into Ukraine's Crimean peninsula over the weekend, Secretary of Defense Chuck Hagel said the situation there risked becoming dangerously unstable.

"This could be a very dangerous situation if this continues in a very provocative way," Hagel said in an interview, recorded Friday, with CBS's Face the Nation. "We have many options, like any nations do. We're trying to deal with the diplomatic focus. That's the appropriate responsible approach and that's what we're going to continue."

Hagel's prerecorded remarks came before the Russian parliament on Saturday unanimously voted to send troops into Ukraine. Responding to that action, Secretary of State John Kerry called on Russia to withdraw its troops, warning that it could face stiff sanctions from the international community if it failed to do so.

A neo-Nazi march is scheduled for Saturday in the small Georgia city of Newnan, about 40 miles southwest of Atlanta. Anti-fascist counter-protesters are expected as well, and a local church will hold an interfaith service to promote "peace and unity" during the rally.

To prepare for the event, local shopkeepers have removed anything that could be moved or thrown in public spaces, and many will not open for business to decrease opportunities for conflict. Many Newnan residents went shopping the night before to help make up the missing revenue.

And a community nonprofit invited children to make chalk drawings in the local park to undermine the neo-Nazis' message: "It will be hard for the hate group to take serious video footage when a rainbow-colored unicorn is in the shot." Bonnie Kristian

An estimated 1,500 mourners turned out for the funeral of former first lady Barbara Bush at St. Martin's Episcopal Church in Houston on Saturday.

Her widower, former President George H.W. Bush, was joined by former President George W. Bush and his wife, Laura; former President Barack Obama and his wife, Michelle; and former President Bill Clinton and his wife, Hillary. First lady Melania Trump attended without President Trump — sitting presidents typically do not go to funerals of former first ladies — who tweeted about the funeral from his Mar-a-Lago resort in Florida:

Queen Elizabeth turned 92 on Saturday, marking the day with several military salutes and a concert in the evening. She is the oldest British monarch by more than a decade, easily outpacing runner-up Queen Victoria, who lived to be 81.

Though April 21 is the actual day of her birth, Elizabeth officially celebrates her birthday on June 9, a tradition that dates to King George II, who wanted to celebrate with good weather in the summer instead of his real birthday month, November. The summer birthday is marked with a large parade in London.

On Thursday, Elizabeth formally endorsed her son, Prince Charles, to be the next leader of the Commonwealth. "It is my sincere wish that the Commonwealth will continue to offer stability and continuity for future generations and will decide that one day the Prince of Wales should carry on the important work started by my father in 1949," she said.

Missouri Governor Eric Greitens (R) was charged Friday with felony computer data tampering for his campaign's alleged use of "data, specifically a donor list owned by The Mission Continues," a charity Greitens founded, for "a political fundraiser."

Greitens is already charged with felony invasion of privacy. He is accused of threatening a woman with whom he was having an extramarital affair that he would release an intimate photo of her if she spoke about their relationship.

The governor has refused to resign while his court cases proceed. He denied the new allegations Friday. Bonnie Kristian

The U.S. Centers for Disease Control and Prevention (CDC) on Friday directed Americans to throw away all romaine that could have been grown near Yuma, Arizona, which is believed to be the source of E. coli contamination on the lettuce. The CDC originally warned against pre-chopped romaine only, but the caution has been expanded to include hearts of romaine and full heads of the lettuce.

Some 53 people in 16 states have been affected by the outbreak. While five have suffered kidney failure from the bacteria, no deaths have been reported so far. Read the CDC's full report on the outbreak here. Bonnie Kristian

A California man named Anthony Mele was killed in an apparently random stabbing attack while he held his young daughter at a cafe in Ventura, California, on Wednesday.

A homeless man named Jamal Jackson was arrested and charged with first-degree murder for the attack. Restaurant employees and customers followed Jackson after the stabbing to help police locate him.

"It's horrible," said prosecutor Richard Simon. "You don't think you're going to be killed when you go out to dinner at a nice restaurant with your family." Bonnie Kristian

In rapid-fire tweets Saturday morning, President Trump accused New York Times reporter Maggie Haberman — who co-wrote a Friday story on Michael Cohen, Trump's personal attorney — of faking the report in an effort to coerce Cohen into talking to Special Counsel Robert Mueller's Russia probe:

Trump posted his tweet series twice, the second iteration replacing a first attempt in which Trump misspelled "Haberman" as "Habberman."

The Times story in question suggests Cohen's loyalty to Trump may be fading after years of Trump treating him "poorly, with gratuitous insults, dismissive statements and, at least twice, threats of being fired." "Donald goes out of his way to treat [Cohen] like garbage," said Trump adviser Roger Stone. Bonnie Kristian
