Trump isn't the only senior White House official rooting for Brexit. National security adviser John Bolton talks regularly by phone with his Brexiteer friends inside Theresa May's imploding government — Cabinet ministers Liam Fox and Chris Grayling — according to a May government source.

What they're saying: "John is a strong believer in Brexit and has been encouraging the Brexiteers to keep it up," the source told me.

Bolton has never disguised his contempt for the European Union, and he's long advocated for a clean Brexit.

He did so as a Fox News commentator long before joining the Trump White House, and he's done so both privately and publicly as national security adviser.

  • "God bless the people of Great Britain who two years ago voted to get out of the European Union," Bolton said in a September speech.

Between the lines: We already knew that Bolton channels Trump in a way that differs dramatically from his predecessor, H.R. McMaster (see Bolton's stances on Iran, the UN and the International Criminal Court). But his pro-Brexit cheerleading may be his Trumpiest turn yet.

A spokesman for Bolton declined to comment.

The Supreme Court ruled early Tuesday that federal executions can resume, reversing a lower court decision and paving the way for the first lethal injection since 2003 to take place at a federal prison in Indiana, AP reports.

The big picture: A lower court had delayed the execution, saying inmates had provided evidence the government's plan to carry out executions using lethal injections "poses an unconstitutionally significant risk of serious pain."

More Republicans say they're wearing masks

Data: Axios/Ipsos poll; Chart: Andrew Witherspoon/Axios

Nearly two-thirds of Americans — and a noticeably increasing number of Republicans — say they’re wearing a face mask whenever they leave the house, according to the latest installment of the Axios-Ipsos Coronavirus Index.

Why it matters: A weakening partisan divide over masks, and a broad-based increase in the number of people wearing them, would be a welcome development as most of the country tries to beat back a rapidly growing outbreak.

Buildings are getting tested for coronavirus, too

Testing buildings — not just people — could be an important way to stop the spread of the coronavirus.

Why it matters: People won't feel safe returning to schools, offices, bars and restaurants unless they can be assured they won't be infected by coronavirus particles lingering in the air — or being pumped through the buildings' air ducts. One day, even office furniture lined with plants could be used to clean air in cubicles.
