Connecticut Senator Joe Lieberman will introduce a Senate measure to repeal “don't ask, don't tell,” the 1993 policy that bans gay troops from serving openly, Wednesday at 12:30PM.

Joining the Independent senator will be Democratic Senators Kirsten Gillibrand of New York, Carl Levin of Michigan, Mark Udall of Colorado and Roland Burris of Illinois.

Lieberman and Gillibrand have become outspoken gay allies of repeal in the Senate. Levin is the chairman of the Senate Armed Services Committee, the bill's most likely destination. The committee's ranking Republican is Arizona Senator John McCain, who has become the Republican face of opposition to repeal.

The measure will be introduced at a press conference hosted by Virginia Senator Jim Moran, a Democrat. Moran's event will feature “a number of service men and women who will share their personal experiences under DADT,” according to a statement released to the press.

A House version of the bill was introduced last year and has attracted 189 cosponsors. Pennsylvania Representative Patrick Murphy, a Democrat, took over sponsorship of the measure after California Representative Ellen Tauscher accepted an appointment in the Obama administration.

The Pentagon's top brass, including Defense Secretary Roberts Gates and Admiral Mike Mullen, chairman of the Joint Chiefs, have publicly announced they support President Obama's pledge to end the policy, but service chiefs from the various armed forces have testified against repeal or have expressed trepidation. Secretary Gates has called for a study on the issue.

Several House members will also attend the event, including openly gay Jared Polis, a Colorado Representative, and Democratic Representatives Mike Honda of California, Jerrold Nadler of New York, and Lois Capps of California.

Major Mike Almy, who was discharged under the policy after 13 years of Army service, will also participate.
