Clinton Has Another Coughing Episode at CNN Dem Townhall

Whatever's causing Hillary Clinton's persistent, hacking cough struck again last night. Appearing in CNN's Democratic Townhall in Columbia, S.C., the 2016 front-runner fell victim to another hack attack just as the event began wrapping up.

As host Chris Cuomo began thanking the assembled audience, Clinton interrupted with the same nagging cough that's dogged her throughout the campaign.  

Take a look.

CLINTON: "I will serve you with the utmost of my ability and commitment to making this country all it should be for everyone who’s in it. Thank you very much."
CUOMO: "Secretary Clinton, thank you very much. We thank all of you, we thank the candidates. Special thanks to the voters--"
CLINTON: [coughing]
CUOMO: "--For asking such great questions. Thanks to the viewers at home and everybody here in Columbia for their amazing hospitality."
