Senator John McCain has been one of the most influential political voices for decades. The Arizona senator partnered with HBO to give that voice a new platform in an illuminating profile about McCain's political life through the new documentary "For Whom the Bell Tolls."

The bottom line: As McCain continues to fight brain cancer, this documentary shows us his triumphs and mistakes as a senator as well as a glimpse into his thinking while living with his diagnosis.

McCain talked about his cancer diagnosis in the documentary and wanting to know how long he has to live.

"These doctors keep talking to me about people, if you tell them the truth, then they give up and die...I keep saying to them, just tell me. Just tell me. That's all I want to know."
"I talk to other doctor friends of mine and they say that's not what most people want to hear. Why wouldn't they want to hear? Why wouldn't they want to spend a few more days here."

He tells the story of when he was captured and held as a prisoner of war in Vietnam.

"A missile took the wing off the airplane. The army came and took me to the prison camp. And one of the interrogators, he said 'things will be very bad for you now, McCain.'"

McCain talks about doing what he believes is right in government and the state of the government today giving a slight rebuke of how things are being run currently, without mentioning President Trump by name.

"We need to give the American people what they deserve. And right now, they're not getting it."

Indoor air is the next coronavirus frontline

A growing body of research has made it clear that airborne transmission of the coronavirus is possible.

Why it matters: That fact means indoor spaces can become hot spots. Those spaces also happen to be where most business and schooling takes place, so any hope for a return to normality will require better ways of filtering indoor air.

Online learning can be frustrating for students, teachers and parents, but some methods are working.

The big picture: Just as companies are using this era of telework to try new things, some principals, teachers and education startups are treating remote learning as a period of experimentation, too.
