Good morning, NBC News readers.
This morning we are looking at why the backlash to "vaccine passports" matters, the new NCAA champs and the latest in the GOP battle against some corporate and cultural giants.
Here's what we're watching this Tuesday.
'Vaccine passports' are a hot-button issue for the GOP. Some experts worry it may fuel hesitancy.

Growing conservative backlash to the idea of "vaccine passports" —proposed by some private-sector industries to promote a safer environment as states begin to ease coronavirus restrictions — could make Republicans even less likely to get their shots, experts warned.
The notion has come under intense scrutiny on Fox News and among conservative politicos and pundits for more than a week.
Conservatives have criticized the so-called passports in the same way they attacked earlier government restrictions, like lockdowns and mask mandates, as potential government overreach and a violation of patient privacy — a point the American Civil Liberties Union has echoed.
But public health experts fear the debate could jeopardize the larger goal of the U.S. ultimately achieving herd immunity, which scientists estimate will be reached when 70 percent to 85 percent of the population has Covid-19 antibodies.
"The idea of a vaccine passport has become politicized quickly, making it a wedge separating people rather than a bridge to our goal of increasing vaccination," said epidemiologist Brian Castrucci.

By Janelle Griffith | Read more
In a rare instance of a police chief testifying against an officer, Minneapolis Police Department Chief Medaria Arradondo rebuked Derek Chauvin from the witness stand Monday for his behavior during George Floyd's arrest. "Clearly when Mr. Floyd was no longer responsive and even motionless, to continue apply that level of force to a person," Arradondo testified, "that in no way, shape or form is anything that is by policy. It is not part of our training, and it is certainly not part of our ethics or values." By Janelle Griffith | Read more
