The "Respect for Marriage" Act which would repeal DOMA, will be discussed in the Senate Judiciary Committee today. This effort is welcome, but in the current climate, somewhat quixotic. From Wikipedia:

The 2011 bill was introduced by U.S. Representative Jerrold Nadler of New York on March 16, 2011, and a U.S. Senate version was introduced by Dianne Feinstein of California on the same day. President Obama announced his support for the bill on July 19, 2011.[3] In September 2011, Ileana Ros-Lehtinen of Florida became the 125th cosponsor of the bill in the U.S. House of Representatives and the first Republican member of the U.S. Congress to announce support for the bill.

From MSNBC:

A committee vote could happen Nov. 3rd, but is more likely a week later. All 10 committee Democrats support repeal of DOMA, but the bill's prospects are less certain in the full Senate. It faces virtually certain defeat in the Republican-controlled House.
