This from USA Today: President Obama is likely to sign the repeal of the military's "don't ask, don't tell" policy Wednesday, and may hold a news conference this week, spokesman Robert Gibbs said today.

Officials have discussed a presidential news conference after the Senate wraps up its end-of-the-year business, including the proposed arms cut treaty with Russia -- but no one knows when that might happen.

A news conference is "certainly possible," Gibbs said.

Though the schedule is being finalized, Gibbs said he expects a formal White House signing ceremony Wednesday morning to sign the "don't ask, don't tell" repeal.

"I think there are a lot of people who are interested in attending," Gibbs said.

Gibbs said White House and Pentagon lawyers are working on "implementation and legal issues" associated with lifting the ban on gays in the military.

As the Senate voted Saturday to end "don't ask, don't tell," Obama praised members for "ending a policy that undermines our national security while violating the very ideals that our brave men and women in uniform risk their lives to defend."

Obama said:

It is time to recognize that sacrifice, valor and integrity are no more defined by sexual orientation than they are by race or gender, religion or creed. It is time to allow gay and lesbian Americans to serve their country openly.
