The Obama administration on Friday is expected to certify repeal of “Don't Ask, Don't Tell,” the 1993 law that bans gay and bisexual troops from serving openly.

Various sources are reporting that the White House received certification from the Pentagon on Thursday and that President Barack Obama will follow on Friday.

Certification is the last hurdle needed to scuttle the law that has ended the military careers of more than 13,000 service members.

The policy will officially end sixty days after certification.

Aubrey Sarvis, executive director of Servicemembers Legal Defense Network (SLDN), the largest group lobbying for repeal, welcomed the move.

“This Pentagon certification received by the White House this afternoon is welcomed by gay and lesbian service members who have had to serve their country in silence for far too long,” Sarvis said in a statement. “The troops and the commanders are ready. Our nation's top military leaders have testified that commanders see no significant challenges ahead.”

“The official certification to Congress that the armed forces are prepared for the end of 'Don't Ask, Don't Tell' should go to Capitol Hill tomorrow with the president's signature,” he added.
