This is CNN breaking news.

You are looking live at Temple University in the great city of Brotherly Love, Philadelphia, where in just minutes Vice President

Kamala Harris and her freshly picked running mate, Minnesota Governor Tim

Wall's, will make their very first joint appearance as the Democratic ticket for president and vice president.

Welcome to the lead.

I'm Philly zone, Jake Tapper.

where Trump will overperform if passed his precedent

in the rural counties and townships,

making it vital for the Democrats to rack up as many votes as they can here in

Philadelphia and the surrounding suburbs, the so-called collar counties, Vice President

Harris as of last night had not decided whom she would

pick to serve as her own Vice Presidential running mate so we're told she slept on it. She

Moments ago, Vice President Harris posted a video of the phone call she made to walls to officially

offer him the spot on the ticket.

Take a look.

I would be honored Madam Vice President the joy that you're bringing back to the country

the enthusiasm that's out there it would be a privilege to take this with you across the

country.

Walls has had a fairly progressive record as Minnesota's governor.
