Republican National Committee deputy communications director Tim Miller on Monday mocked the lack of diversity in President Barack Obama's second-term cabinet nominations, taking to Twitter to refer to Sen. John Kerry (D-MA), former Sen. Chuck Hagel (R-NE) and the administration's current counterterrorism adviser John Brennan as "3 old white guys who supported/voted for Iraq & DADT."

To review: Obama to nominate 3 old white guys who supported/voted for Iraq & DADT to top foreign policy cabinet slots. #Forward(ish)
