From NBC's Savannah Guthrie
Vice President-elect Biden wasn't in Washington today just to meet with the bipartisan commission on weapons of mass destruction.
He also met with Microsoft founder Bill Gates at the transition offices here. (We'll update with details as we get them.)
*** UPDATE *** A transition source says Biden and Gates met to "discuss a wide-range of issues, including global health and development, as well the need to improve resources for secondary education, particularly for community colleges."
So, there you go.
