Welcome to the beat. I'm Jason Johnson and for Ari Melber. We start with the wild contrast in mood and momentum between two campaigns.

The pictures tell the story.

Kamala Harris and Joe Biden holding a raucous campaign event with a fired up crowd.

Hours later, Donald Trump holding a solo press conference amid criticism from his own allies that he's sputtering and

flailing on the campaign trail.

Biden and Harris appearing in Maryland, their first joint event since Biden dropped out.

It was billed as a White House event about Medicare

and prescription drug prices, which might sound kind of dry, but the energy was high.

Here was the long line outside in the middle of a Thursday afternoon and trust me I

know Largo Maryland that is hard to get there by traffic. Harris and Biden literally

embracing each other on stage the crowd was also feeling the love.

And today we take the next step.

Thank you, Joe, forward in our fight. We can't you go,

and you know,

and you know,

and you know,

and you know, and you know. Biden and Harris both shouting each other out.

It is my eternal and great great honor I have to tell you to serve with this most extraordinary

human being.

Thank you, Kamo.

So I could speak all afternoon about the person that I am standing on this stage with.

Folks, I have an incredible partner, the progress we've made, and she's going to make one hell of a president.
