"Many of us were in the East Room watching the president, we’ve seen him on many occasions where he had a repeated cough. What is the situation with that cough and is it a concern?" NBC News’ Kelly O’Donnell asked Psaki.

"I don't think it's an issue of concern," Psaki said. "There's a range of reasons why we need to clear our throat or have a light cold."

Psaki said that Biden has a doctor who travels with him and he is checked regularly.

Q    One very different — separate.  Many of us were in the East Room watching the President.  We’ve seen him on many occasions where he has a repeated cough.  What is the situation with that cough?  And is that a concern?

MS. PSAKI:  It’s not a concern.  We have a doctor who travels with him, obviously, who checks in if there is — it is ever warranted.  And certainly, that continues to be the case, as it has been since the beginning of his presidency.

Q    Is there an explanation for why he coughed so frequently in situations like that?  I’m sure you saw it.

MS. PSAKI:  I did.  I don’t think it’s an issue of concern.  I think there are a range of reasons why we may need to clear our throat or we may have a little light cold.  And that’s certainly something that presidents, elected officials, reporters, spokespeople can confront, but it’s not an area where we have a medical concern. 

Go ahead.
