On the February 7 edition of MSNBC's Morning Joe, co-host Mika Brzezinski asked presidential historian Doris Kearns Goodwin: "[A]t this moment in history, isn't [Sen.] John McCain [R-AZ] the perfect candidate to deal with what challenges we face as a country, and given the presidency that is just coming to a close right now?" At no point during the segment, however, did Brzezinski disclose that her brother is a McCain adviser.

Brzezinski has previously informed viewers that her brother Ian works for the McCain campaign and that her father, former national security adviser Zbigniew Brzezinski, and another brother, Mark, advise Democratic presidential candidate Sen. Barack Obama (IL). On the January 3 edition of Morning Joe, after co-host Joe Scarborough said, “And by the way, your dad involved, once again, very much so, in the Obama campaign,” Brzezinski responded, “And my other brother an adviser to McCain. I feel like I need to say that.” On December 21, 2007, after an appearance on Morning Joe by Obama, Brzezinski said, “I just always have to point out when we have Senator Barack Obama on that my father and my brother advise him on foreign policy. And for the record, I have another brother who works for McCain.”

From the February 7 edition of MSNBC's Morning Joe:

BRZEZINSKI: All right, Doris, so here's my thing. I just -- I still -- I understand the parts about John McCain that some of the conservative base may have a problem with. At the same time -- and this is a question that's perfect for you -- at this moment in history, isn't John McCain the perfect candidate to deal with what challenges we face as a country, and given the presidency that is just coming to a close right now?
