Rebekah Mercer, a primary financial supporter of Steve Bannon and Breitbart News, has released a statement saying she and her billionaire father have not spoken to Bannon "in many months" and do not support his "recent actions and statements," after Bannon attacked President Trump and his family in interviews for a forthcoming book, per the Washington Post.

Meanwhile, the Mercers and other Breitbart board members have seriously discussed removing Steve Bannon as chairman of Breitbart due to his feud with Trump, the Wall Street Journal reports and Axios' Jonathan Swan has corroborated.

Why it matters: If the Mercers abandon Bannon he'll be left without the main funders of his political activities, harming his ability to take on the GOP establishment in this year's midterm elections. Mercer said in the statement that her family has "provided no financial support to [Bannon's] political agenda" in recent months.

Biden confronts mounting humanitarian crisis at the border

Just over a month into his presidency, President Biden is staring down a mounting crisis at the border that could be just as bad as the ones faced by Barack Obama and Donald Trump, if not worse.

Why it matters: Immigration is an issue that can consume a presidency. It's intensely and poisonously partisan. It's complicated. And the lives and welfare of vulnerable children hang in the balance.

The rise of vaccine passports

Vaccine passports were touted early in the pandemic as an important piece of the plan to get people back to normal life. Now they’re becoming a reality.

Driving the news: CLEAR, the secure digital identity app that you see in airports around the world, and CommonPass, a health app that lets users securely access vaccination records and COVID test results, have joined forces.

"Vaccine tourism" stretches states' supplies

Americans who are highly motivated to get vaccinated are traveling across state lines after hearing about larger vaccine supplies or loopholes in sign-up systems.

Why it matters: "Vaccine tourism" raises ethical and legal questions, and could worsen the racial socioeconomic and racial inequalities of the pandemic.
