Bernie Sanders, Democratic establishment battle boils over.

It was really just a matter of time.

With the Democratic presidential primary in its twilight, frustration within the ranks over the party's handling of the primary process spilled out this week as Bernie Sanders supporters lashed out at party leaders, arguing that their candidate has been treated unfairly.

The public outpouring of anger began last weekend at the Nevada Democratic Party convention, where Sanders supporters who said Hillary Clinton's backers had subverted party rules shouted down pro-Clinton speakers and sent threatening messages to state party Chairwoman Roberta Lange after posting her phone number and address on social media.

First missing Chibok girl found after 2 years as Boko Haram prisoner.

When Amina Ali Nkeki was kidnapped by the Nigerian terrorist group Boko Haram more than two years ago, she was a mere schoolgirl.

On Tuesday night, she apparently wandered out of a forest, asking for help -- accompanied now by a "husband" and a baby.

She is the first of the more than 200 Chibok schoolgirls kidnapped by Boko Haram to be freed after the two years in captivity, Nigerian military officials and a witness say.

Military officials and locals gave different accounts of how she was liberated. Nigeria's army said she was rescued by army troops, but a witness told CNN the girl wandered out of the Sambisa Forest in the northeast of the country along with her child and a man.

The Sambisa Forest, believed to be the terrorist group's stronghold, has long been the suspected location of the girls. As many as 276 of them were kidnapped at gunpoint from their boarding school in Chibok in Borno, northeast Nigeria, on April 14, 2014.

At least 57 girls were able to escape soon after their abduction, but more than 200 of them remain missing.
