"Key concerns include whether currently enlisted troops have had medical or other issues that cause delays or problems with their ability to deploy or meet physical or other standards for their jobs. Military leaders also wanted to review how transgender troops are treated, if they’re discriminated against or if they have had disciplinary problems, the officials said."

You'd think U.S. leaders would try to get answers on these issues before announcing anything as draconian as a total ban. Although Trump appears to like bans, which he presumably believes make him look authoritative and decisive, the announcement seems intended as "red meat" to appeal to the most regressive views held by some of his supporters.
