Three big wins last night for former vice president Joe Biden taking Florida, Illinois and Arizona.

Biden widened his lead over Senator Bernie Sanders, who says he is not suspend suspending his campaign but is having conversations with supporters in the days ahead.

NBC's political director, Rick Klein, joins us now with more Rick.

So what?

Sanders strategy.

Moving forward.

Lindsay.

The race is effectively over Joe Biden, very likely to be the nominee, and the Sanders camp knows that the math is stubborn.

The question is how soon he decides to do something about that.

There are conversations we understand they're gonna be going on between his camp and Biden's camp at some point to try to negotiate what can be done from here.

We also know that spending a lot of time working on the response to the Corona virus.

He's going to be in the Senate himself these next couple of days, working sometimes with his former rival, perhaps Senator Elizabeth Warren, to try to craft this government response.

But realistically speaking, he has no shot at becoming the nominee, and he can't even really campaign.

All campaigning remains suspended on.

There may not even be any voting of any substance for at least six weeks.

So right now the campaign is a bit in limbo.

But Joe Biden emerging stronger Bernie Sanders without a path.

And just moments ago, we learned about the first congressman to test positive for Cove in 19.

Tell us more about that.

Yeah, this is a big headline.

Enough.

Congressman Mario Diaz Balart.

Ah, veteran lawmaker, Republican from South Florida.

Ah, part of the story.

Diaz Balart, Family in Florida, Cuban American politics.

He tested positive.

Hey, has said that he was self quarantining since Saturday, when he started to feel ill.

Came back with that positive test today.

But here's the thing, Lindsay.

He was voting in the House of Representatives overnight Friday into the early wee hours of Saturday morning.

They were more than 400 members of Congress on the House floor, plus assorted staff.

This is going to send a chill through the halls of Capitol Hill, where they're continuing to work on legislation even as they deal with the potential exposure that information like this means.

Alright, Right.

Klein, Thank you so much for that.
