Political surrogate Nina Turner says heart attack won't stop Bernie Sanders from resuming campaign

One of 2020 Democratic presidential candidate Bernie Sanders' most vocal supporters told ABC News' "Powerhouse Politics" podcast that not even a heart attack will stop Sanders from campaigning.

Nina Turner, a surrogate and national co-chairwoman for the Sanders campaign and a former Ohio state senator, told Deputy Political Director MaryAlice Parks and Multi-platform Correspondent Serena Marshall that his staff and supporters will have to step up, rally around him and do more campaigning on his behalf until he gets back to full speed.
