'You don't say': CDC director confesses that 'borders can be porous'

He said it:

CDC's Frieden on possibility of travel ban: "Right now we know who's coming in." But later says "borders are porous." #EbolaHearing

CDC director Frieden implies that if you impose a travel ban, Ebola-infected people will sneak into the U.S. "Borders can be porous."

— Matt Fuller (@MEPFuller) October 16, 2014

Well, yeah. That’s part of the problem, no?

Borders can be porous-dr. Frieden (oh, really, you don't say..)

Only thing honest I heard so far is "borders can be porous especially in this part of the world" #ebolahearing #secureOurBorder

A follow-up question from Rep. Marsha Blackburn gave Frieden the opportunity to explain what he meant:

Frieden clarifies that he was referring to “porous borders” in Africa after GOP Rep. Blackburn seizes on his comments

Blackburn asks about Frieden's porous border comment. He says he was referring to the borders of African countries.

— Matt Fuller (@MEPFuller) October 16, 2014

OK, well, if that’s indeed what he was trying to say … how is it supposed to make us feel better, exactly?
