More than three-fourths of Americans favor repealing "Don't ask, don't tell," according to a new CNN poll.

A full 78 percent of respondents said that "people who are openly gay or homosexual" should be able to serve in the armed forces. The results are similar to what CNN found in December of 2008 (81 percent) and May of 2007 (79 percent).

The findings come as Congressional leaders have reportedly reached a deal with the White House on a repeal of the policy.

As Roxana Tiron reports:

Under the deal, the ban on gays serving openly in the military would be repealed once a Pentagon working group studying repeal has completed its review.

President Barack Obama, Secretary of Defense Robert Gates and Chairman of the Joint Chiefs of Staff Adm. Mike Mullen must also certify that repeal can be achieved “consistent with the military’s standards of readiness, effectiveness, unit cohesion and recruitment and retention,” according to a letter to the White House signed by the chief backers of repeal in Congress, Rep. Patrick Murphy (D-Pa.), Senate Armed Services panel Chairman Carl Levin (D-Mich.) and Senate Homeland Security Committee Chairman Joe Lieberman (I-Conn.), who is also a senior member of Levin’s panel.
