“There are bans that are still up at the Supreme Court right now to keep Muslims out of America,” she added, as well as efforts to “kick patriotic trans people out of the military. And that’s coming from the Oval Office right now.”

Ms. Reid’s posts emerged on social media this month via the Twitter user @Jamie_Maz. In December, the same account shared posts in which Ms. Reid taunted Charlie Crist, the Democratic former Florida governor, as a closeted gay man whose heterosexual marriage was a political front. Late last year, she apologized and Mr. Crist responded, “Long forgotten, but thank you, Joy. I appreciate you.”

It’s not the first time Ms. Reid’s words have stoked controversy.

On Saturday she apologized for some of her past tweets, including ones in which she mocked the conservative commentator Ann Coulter by “using transgender stereotypes.” Ms. Reid grew up in a household that had conservative values on L.G.B.T. issues, she said, but “those tweets were wrong and horrible.”

“I look back today at some of the ways I’ve talked casually about people and gender identity and sexual orientation and I wonder who that even was,” she added. “But the reality is that like a lot of people in this country, that person was me.”

She did not take ownership of the most recently surfaced blog posts, however. In a statement this week to Mediaite, Ms. Reid said that her website had been breached and that the posts were fabricated by hackers intending to defame her.

She said in the statement that “an unknown, external party accessed and manipulated material from my now-defunct blog,” and that she had retained an online security expert to investigate. “I can state unequivocally,” she wrote, that the resurfaced posts do “not represent the original entries.”

Ms. Reid’s former blog posts were discovered via the Wayback Machine, an archive of more than two decades of web history. On Tuesday, the Internet Archive, which runs the Wayback Machine, responded to Ms. Reid’s claim that her posts had been hacked, saying in a statement that it had found no evidence of hacking in the archived versions of her site.
