It's not often that former presidential candidate Sen. Bernie Sanders has a live interview interrupted with, "Sorry, that's my Momma calling."

But it's rare that Sanders takes a live interview with Cardi B from their respective quarantines during the coronavirus, a wild event that actually happened on Twitter and Instagram Tuesday.

Cardi B has been an outspoken supporter of Sanders, referring to him as "Uncle Bernie." Their discussion, after Sanders dropped out of the campaign and endorsed Joe Biden, was a collision of massive social media audiences: Cardi has 62.6 million Instagram followers, to Sanders 4.9 million.

The rapper had plenty to say in the interview, despite the interruptions, and even managed to turn long statements into questions.

"One thing that baffles my mental, right, about number 45," Cardi B said, refusing to refer to President Donald Trump by name, "is that, when this coronavirus news was hitting and everything, he just kept blaming, that this was a move by the Democrats to make him look bad. That everything the Democrats do is bad propaganda to make him look bad."

“Honey, you don’t need the Democrats to make you look bad. You make your own self look bad," she continued in a rant that Sanders eventually was able to break into and answer about Trump.

In another, actual question, Cardi B asked Sanders about his endorsement of Biden for president.

"A lot of people like the youth, they don’t rock with Joe Biden, because he’s conservative," she said, eventually getting to. "I want you to explain to my platform, why are you endorsing him?"

Sanders answered that Trump was "a bad-news guy that has got to be defeated" and that he vowed to support the Democratic candidate that prevailed. He also vowed to "work with Joe" to make him more progressive.

Another out-there interview moment featured the resplendently nailed rapper looking at Sanders' fairly less flashy fingernails.

"I can tell you’ve been in quarantine for a while now, with those nails," she said, "It’s OK, Uncle Bernie."

Twitter, too, had its collective mentals baffled by the interview. In the words of one user, "honestly, I’m not even confident this is real life anymore."

"Bernie Sanders and Cardi B livestreaming from quarantine is peak 2020," tweeted @joshdecker97.

"bernie sanders is live with cardi b the simulation is glitching," said @kimmyvaine.

"Quarantine day number...Bernie Sanders asking Cardi B how his nails look," said @ChicksInTheOff.

"Cardi B and Bernie Sanders went live on Instagram together and I will never be the same," wrote user @bigboiibibby.

This is not the first time the star and Sanders have collided on the public stage.

Last summer, Sanders teamed up with Cardi on a video aimed at attracting the support of young voters.

And in January, Cardi B took to Twitter and discussed running for office and how she would tackle issues like gun control.

"Cardi B is deeply concerned about what's happening in the country," the 78-year-old Vermont senator told TMZ ahead of the Democratic debate in Iowa. "She knows what it's like to live in poverty and struggle, and it would be great for her to bring that experience to politics."
