A federal judge on Tuesday temporarily blocked the U.S. military from enforcing President Donald Trump's executive order barring transgender people from military service while a lawsuit by 20 current and would-be service members challenging the measure goes forward.

The Pentagon cannot enforce President Donald Trump’s order banning transgender people from serving in the military, a federal judge ruled Tuesday, saying it is “soaked in animus” and unconstitutionally discriminates on the basis of sex.

The order allows soldiers to keep serving in the military under rules established by the Biden administration.
