Military chiefs will seek a six-month delay before letting transgender people enlist in their services, officials said Friday.

After meetings this week, the service leaders hammered out an agreement that rejected Army and Air Force requests for a two-year wait and reflected broader concerns that a longer delay would trigger criticism on Capitol Hill, officials familiar with the talks told The Associated Press.

The new request for a delay will go to Defense Secretary Jim Mattis for a final decision, said the officials, who weren’t authorized to discuss the internal deliberations publicly and spoke on condition of anonymity.

Transgender servicemembers have been able to serve openly in the military since last year, when former Defense Secretary Ash Carter ended the ban, declaring it the right thing to do. Since Oct. 1, transgender troops have been able to receive medical care and start formally changing their gender identifications in the Pentagon’s personnel system.
