Vice President Kamala Harris campaigned Monday in battlegrounds Pennsylvania, Wisconsin and Michigan with former Republican congresswoman Liz Cheney. Chris Matthews joins Morning Joe to discuss Cheney's support for Harris: “I've never seen a more heroic figure than Liz Cheney.

She gave it all away in the interest of truth— There's such courage there." » Subscribe to MSNBC: on.msnbc.com/SubscribeTomsnbc About: MSNBC is the premier destination for in-depth analysis of daily headlines, insightful political commentary and informed perspectives.
