CBS THIS MORNING: Sen. Bernie Sanders is getting a major boost to his presidential campaign after his heart attack nearly three weeks ago. The left-wing congresswoman, Alexandria Ocasio-Cortez, endorsed him in front of more than 25,000 people at a weekend rally in New York City.



CBS News’ Nikole Killion spoke with them in their first joint network interview after the announcement and asked the freshman Congresswoman why she is supporting "an old white guy" like Sen. Bernie Sanders.







NIKOLE KILLION, CBS NEWS: You made history with your election and you both are part of the most diverse Congress in history. This is also the most diverse Democratic presidential field ever. I am going to be a little blunt with you, Congresswoman, and don't take offense, Senator. But as a woman of color, why back an old white guy and is this the future of the party?



REP. ALEXANDRIA OCASIO-CORTEZ (D-NY): Yeah. I'm actually a little excited about this partnership because it shows what we have to do in our country. We have to come together across race, across gender, across generation, and across class in order to establish our basic systems as rights.
