Despite tweeting earlier this month that she was taking a temporary break from Twitter, the 27-year-old actress returned to the app on Wednesday to share her views on Trump's controversial decision.
"Don't thank us for your harmful inanity when you're actually bowing to the hall of carnival mirrors that is your brain," Zelda wrote in reply to Trump's announcement. "Whatever he enacts, to watch the President publicly reduce soldiers, whatever their orientation, to financial burdens... disgraceful."
She then told fans she originally was not planning on using the app again until Aug. 11, the three-year anniversary of the death of her father, Robin Williams.
"He loved our soldiers & veterans more than anyone I'll likely ever meet," Zelda explained. "Dad spent many Christmases in Iraq entertaining our troops, even when he was at risk himself. They are humans Mr. President. Not bar tabs."
"So don't thank us for reading your inane tweets, or yourself for tweeting. Thank them for their service, Mr. President, & let them serve," she continued in a series of tweets. "Anywho, back to my break. Call me whatever you want, just enjoy a delightfully long delay for one of my quippy rejoinders. #KThxBai."
Trump tweeted on Tuesday that after consultation with his "Generals and military experts, the United States Government will not accept or allow transgender individuals to serve in any capacity in the U.S. Military."
"Our military must be focused on decisive and overwhelming victory and cannot be burdened with the tremendous medical costs and disruption that transgender in the military would entail," he added. "Thank you."
The proposed policy is a reversal of the Obama administration's decision that would have allowed transgender individuals to serve.
Of course, Zelda wasn't the only one who had a lot to say about the potential ban. Click HERE
