Kay Hagan Flip-Flops on Ebola Travel Ban

Senator Kay Hagan (D., N.C.) on Friday announced her support for a temporary travel ban on non-U.S. citizens from West African countries affected by the Ebola virus. She claims to have supported such a ban "for weeks," and while she has said in the past that a travel ban might be "one part" of a solution to the Ebola crisis, Hagan never fully embraced the idea, and just days ago dismissed a travel ban as something that "is not going to help solve this problem." Now she's calling it "a prudent step the President can take to protect the American people." So, which is it?
