The US military service chiefs are asking for more time to provide the capability to allow transgender soldiers to enlist. But the final decision will rest with Mattis.
However those in the service may serve openly.
CNN has a news story here but the Washington Post featured it as breaking news Friday afternoon.
The service chiefs seem more comfortable now with cis-gender gay soldiers than they had been two decades ago.
Aaron Belkin at the Palm Center at UCSB (Santa Barbara) called it "don't ask don't tell for transgender troops" in own op-ed.
Kristin Beck had been a Navy seal before becoming a woman. There are times that transgender or fluid people are particularly valuable in intelligence operations.
The Washington Blade has a more detailed story by Chris Johnson, including a proposal by Rep. Vicki Hartzler (R-MO) to resume a ban on openly transgender in the military, in DADT fashion, possibly as part of the defense authorization bill (is what happened in 1993 with the original DADT policy).
