I applaud the Supreme Court’s decision to strike down the Defense of Marriage Act. This was discrimination enshrined in law. It treated loving, committed gay and lesbian couples as a separate and lesser class of people. The Supreme Court has righted that wrong, and our country is better off for it. We are a people who declared that we are all created equal - and the love we commit to one another must be equal as well.

How you staff, particularly the chief of staff, the national security adviser, your White House counsel, how you set up a process in the system to surface information and generate options for a president, understanding that ultimately the president is going to be the final decision-maker.
