tenure, he was responsible for the appointment of multiple African-American officers to the highest ranks of the military, including the appointment of General Lloyd Austin, now the first black secretary of defense, as Director of the Joint Staff. On March 18, 2009, Gates recommended to President Barack Obama that Mullen be re-nominated for a second term as chairman of the Joint Chiefs. He was unanimously confirmed by the Senate on September 25, 2009 and began his second term on October 1, 2009. On February 2, 2010, Mullen and Gates said that they fully supported President Obama's decision to end the "Don't ask, don't tell" policy, which prevented openly gay people from serving in the military.

"No matter how I look at the issue...I cannot escape being troubled by the fact that we have in place a policy which forces young men and women to lie about who they are in order to defend their fellow citizens.
