Donald Trump confirmed it to MSNBC this morning.
"Well, I am embracing the issue, and I'm proud of the issue. I think somebody has to embrace it."
Ironically, his comments came after he took offense that MSNBC host, Savannah Guthrie, brought up the birther controversy before she did any other issue.
HOST SAVANNAH GUTHRIE: If you want to be taken seriously as a presidential candidate, do you think this issue of the president's birth is the most serious issue facing the country that you could use your considerable profile and popularity to raise or does it feed into the perception that this is just kind of a sideshow.
TRUMP: Well, I do think it's a serious issue, Savannah, but I also think that a lot of people, frankly, like yourself, Joe [Scarborough] and Mike [Brzezinski] -- they bring it up as the first question.
.... the fact is that Bill O'Reilly -- the first question he asked me was about the birther....
GUTHRIE: [interrupting] Well, wait a minute, Mr. Trump, you are a sophisticated consumer of media. You know that if you embrace this issue, that is going to catch headlines. You could downplay it.
TRUMP: Well, I am embracing the issue, and I'm proud of the issue. I think somebody has to embrace it.
