A group of 17 transgender members of the Air Force are suing the U.S. government over what they say is the military’s unlawful revocation of their early retirement pensions and benefits.

The Pentagon has rolled out a new policy that will severely undercut the ability for transgender troops who have been banned from the armed forces by the Trump administration to turn to boards of their peers to argue for their right to stay in the military.

The Air Force says in a new memo that transgender airmen ousted under a recent Trump administration directive will no longer have the chance to argue before a board of their peers for the right to continue serving their country.
