""I don't think it's an issue of concern," White House press secretary Jen Psaki said. <blockquote>KELLY O'DONNELL: We've seen [Biden] on many occasions where he has a repeated cough? What is the situation with that cough and is that a concern?...Is there an explanation for why he coughs so frequently in situations like that? I'm sure you saw it.</blockquote>
