"The world's worst humanitarian crisis" is in Yemen, overrun by ISIS and al Qaeda, adjacent to Saudi Arabia in the tip of the Arabian Peninsula, across from the Horn of Africa. Text with a New York Times graphic that's worthy of your click:

"Repeated bombings have crippled bridges, hospitals and factories. Many doctors and civil servants have gone unpaid for more than a year. Malnutrition and poor sanitation have made the Middle Eastern country vulnerable to diseases that most of the world has confined to the history books.""The United Nations [last month] called the situation the world's largest humanitarian crisis, with more than 10 million people who require immediate assistance.""In just three months, cholera has killed nearly 2,000 people and infected more than a half million, one of the world's largest outbreaks in the past 50 years.""If infection numbers continue to rise, researchers fear that the cases could ultimately rival the largest outbreak, in Haiti, which infected at least 750,000 people after a devastating earthquake in 2010.""'It's a slow death,' said Yakoub al-Jayefi, a Yemeni soldier who has not collected a salary in eight months, and whose 6-year-old daughter, Shaima, was being treated for malnutrition at a clinic in the Yemeni capital, Sana."Why it matters: "As the state fails, 'the manifestation of that now is cholera, but there could be in the future other epidemics that Yemen could be at the center of.'"

Republicans pledge to set aside differences and work with Biden

Several Republicans praised President Biden's calls for unity during his inaugural address on Wednesday and pledged to work together for the benefit of the American people.

Why it matters: The Democrats only have a slim majority in the Senate and Biden will likely need to work with the GOP to pass his legislative agenda.

The Biden protection plan

The Joe Biden who became the 46th president on Wednesday isn't the same blabbermouth who failed in 1988 and 2008.

Why it matters: Biden now heeds guidance about staying on task with speeches and no longer worries a gaffe or two will cost him an election. His staff also limits the places where he speaks freely and off the cuff. This Biden protective bubble will only tighten in the months ahead, aides tell Axios.

Bush labels Clyburn the “savior” for Democrats

Former President George W. Bush credited Rep. James Clyburn with being the "savior" of the Democratic Party, telling the South Carolinian at Wednesday's inauguration his endorsement allowed Joe Biden to win the party's presidential nomination.

Why it matters: The nation's last two-term Republican president also said Clyburn's nod allowed for the transfer of power, because he felt only Biden had the ability to unseat President Trump.
