A US court has largely blocked President Donald Trump's controversial ban on transgender people serving in the military. <br/><br/>Mr Trump had, in August, signed an executive order banning transgender people from serving openly, reversing former President Barack Obama's directive allowing them to do so. <br/><br/>The move prompted a flood of lawsuits, many of them filed on behalf of transgender service members or veterans.<br/><br/>US District Judge Colleen Kollar-Kotelly sided in part with a group of transgender service members who sued to block the change, halting Mr Trump's ban on service. <br/><br/>It, however, upheld the Trump administration's move to block the military from paying for gender reassignment surgery.<br/><br/>The order by Kollar-Kotelly temporarily prevents the Pentagon from enacting the ban.
