Lambda Legal on Saturday announced their plans to sue the Trump administration over its recent ban on transgenders serving in the military.

President Donald Trump made the declaration on Twitter on July 26:

When the LGBT organization initially found out about the proposed policy on July 26, they vowed to take immediate action if the policy was adopted.

“Transgender people have served our country honorably for years, making our military stronger and more inclusive. President Trump has shown that no one is safe from his administration’s attacks on LGBT people, not even those who risk their lives to defend our country,” legal director Jon W. Davidson said in a July 26 a statement. “If this disgraceful tweet actually becomes policy, we will sue in a heartbeat.”

According to Lambda Legal, they have teamed up with OutServe-SLDN, an organization that advocates on behalf of LGBT military members around the world.

Sasha Burchett, a transgender military veteran and staff attorney for Lambda Legal, said the policy is "mean-spirited" and the "discriminatory attack on our community is capricious, irrational and clearly driven by anti-LGBT forces in the administration who care more about harming transgender people than keeping our nation safe."

According to Burchett, the move is clear unconstitutional.

Lambda Legal says this move "is dishonorable to the thousands of transgender men and women who are serving our country with courage and who are integral parts of our armed services," Burchett said in a statement. "The safety of all service members - transgender or not - is undermined by a policy like this that distracts from the important missions they have for no valid reason. It is also a slap in the face of the leadership who have worked diligently to develop and implement the current policy which has been in place for more than a year without incident."

According to the organization's website, Lambda Legal was founded in 1973 and is the oldest and largest national organization dedicated to LGBT rights.
