Does Haley still have a chance to beat Trump?

A defiant Nikki Haley resisted calls to end her campaign after suffering back-to-back losses to former President Donald Trump in her bid to capture the GOP presidential nomination. “This race is far from over,” Haley told her supporters Tuesday night after Trump was declared winner of New Hampshire’s first-in-the-nation primary. Haley's vow to stay in the race came two days after Florida Gov. Ron DeSantis quit his campaign and threw his support behind Trump – the latest in a long line of endorsements the former president has collected. In New Hampshire, Haley was trailing Trump 54%-43% with nearly all of the vote counted. But Haley and her supporters insist there is still a pathway for her to capture the nomination. 🗳️ Here's a look at what's next for Haley.

Alabama execution stirs ethical controversy

On Thursday, Alabama is set to carry out the first-ever execution by nitrogen hypoxia on death row inmate Kenneth Eugene Smith. The planned execution raises heated questions about the ethics of using the untried method to execute Smith, who has already been through one unsuccessful execution attempt. If the execution is carried out, nitrogen hypoxia would be the first new method used since 1982, when lethal injection was introduced.

Why is it controversial? Nitrogen hypoxia is a form of execution in which an inmate is deprived of oxygen until they breathe only nitrogen, causing asphyxiation. "But the terms of how it's going to exactly work is still unclear," said Joel Zivot, an associate professor in anesthesiology. 👉 Here's everything to know.
