Uh oh - this could be a bit of a test for President Obama: The office of Dem Rep. Ellen Tauscher confirms that she will introduce legislation today ending the "Don't Ask, Don't Tell" policy - a barrier she says we need to "tear down" so that the military can be "better."

Tauscher will formally announce her plans at a speech she's giving later today at the Center for American Progress, and her office sends over an excerpt of her prepared remarks.

"We have a military that is truly the finest in the world but we can be better," Tauscher will say. "There is one last, final barrier that we need to tear down. We need to end the 'Don't Ask, Don't Tell,' policy."

Politico quoted an anonymous Tauscher aide this morning saying she'd be introducing the measure, and Politico opined that such a move could bedevil Obama - as it did Bill Clinton - at a time he's trying to push through a range of enormous initiatives that will consume a great deal of his political capital.

Tauscher’s office tells me she will address this criticism today.

"Many have asked me why now and I have always said that there is no right time to right a wrong," Tauscher will say. "So, today, I am introducing the Military Readiness Enhancement Act. This bill will once and for all end the discriminatory practices of the Department of Defense. It will allow the men and women who have been administratively discharged to have the opportunity to serve again if they want."

The administration is on record saying that Obama will eventually follow through on this policy, and public discussion of it right now will be grabbed onto by the right, could reveal differences on the issue between Obama and uniformed military and put pressure on the Obama administration to reaffirm his commitment to it.
