One year ago, President Trump used Twitter to announce a ban on transgender troops. Today, the fight to protect transgender service people is still very much alive.

LGBTQ civil rights organizations and activists across social media are using the hashtag # TransBanTweetUp on Thursday to get people talking about Trump's continued attempts to bar transgender people from serving in the U.S. military. Led by Human Rights Campaign and Lambda Legal, the campaign makes strategic use of the president's favorite social media platform to bolster support for transgender troops.

The hashtag is not celebratory so much as strategic: It's meant to carve out a space in the large swath of Trump controversies and bring focus to what remains a strenuous battle.

HAPPY ANNIVERSARY: One year ago today, @realDonaldTrump woke up and decided to launch a far-reaching tweet attack on all #transgender service members with the #TransMilitaryBan. #TransBanTweetUp pic.twitter.com/b0LGLoQEql — Lambda Legal (@LambdaLegal) July 26, 2018

The transgender troop ban is disrespectful and dishonorable to the thousands of transgender service members who are boldly serving our country. RT to join us! #TransBanTweetUp #ProtectTransTroops pic.twitter.com/UxI72kUwSH — LGBT Caucus (@LGBTEqCaucus) July 26, 2018

Various lawmakers have also been using the #TransBanTweetUp hashtag to voice their support.

One year ago today, @realDonaldTrump tweeted a shameful and prejudiced ban on our transgender troops. I continue to stand in support of our transgender service members and recruits who are capable and willing to serve. #ProtectTransTroops #TransBanTweetUp — Rep.

We should thank any Americans who willingly volunteer to put their lives on the line to defend us. The transban is not only unconstitutional, it means qualified people aren't joining the ranks. Thanks @GenderJusticeWA, @HRC and everyone else pushing back together #transbantweetup — Rep. Derek Kilmer (@RepDerekKilmer) July 26, 2018

One year ago today, people from WA & across the nation stood up & let @realDonaldTrump know his plan to ban transgender troops from our military was a non-starter—& we won’t let him forget the sacrifice transgender troops make in service to our country. #TransBanTweetUp — Senator Patty Murray (@PattyMurray) July 26, 2018

This past March, the Trump administration tried once again to bar transgender people from enlisting in the military, after the first ban — which stemmed from Trump's tweets — was ruled unconstitutional in seven separate federal courts. The March ban would not discharge currently serving transgender people. It would, however, bar any new transgender person from enlisting, unless they agreed to serve in the sex they were assigned at birth.

Again, the courts ruled this policy unconstitutional and it failed to go into effect.

The Department of Defense, in its recommendation to Trump regarding how the ban should be enforced, also threatened to discharge currently serving transgender military members if the courts utilized their continued service as proof that transgender people are fit to enlist.

Despite the court rulings, many transgender people report continued difficulty enlisting. For example, SPART*A, an association of LGBTQ recruits, troops, and veterans, claims only 2 out of 140 members trying to enlist have made it into the military, according to the New York Times.

"What people need to know is that Trump-Pence administration is trying every which way to create a hostile work environment for transgender people in the military" explained Sarah McBride, HRC's national secretary, "they are banning coverage for transition related care for trans troops, holding the threat of discharge over their heads should a court try to utilize their service to demonstrate their fitness, and just being generally demeaning and disrespecting their service by saying trans folks are unfit when they clearly aren't."

Indeed, the video below depicts a court hearing where all four service chiefs dismissed claims that transgender people in the military had a negative impact on unit cohesion or discipline.

The Human Rights Campaign remains optimistic that Trump lacks the political power to win this fight.

On the anniversary of Trump's initial tweet storm, the tweet up campaign aims to send the exact opposite message: "that transgender people are serving in the U.S. military with distinction, that they are well-respected by their peers" explained McBride, adding, "a great nation respects the service of all military members even when their president refuses to do so."
