No, Trump's sister did not publicly back him. He was duped by a fake account.
On Friday morning, President Trump shared a seemingly innocuous article on Twitter. The piece said that his sister, Elizabeth Trump Grau, had publicly voiced her support for her brother amid his baseless claims that he won the 2020 election.
“Thank you Elizabeth,” Mr. Trump wrote to his sister, who has long avoided the spotlight. “LOVE!”
There was just one problem: Ms. Trump Grau had not said what the article claimed. In fact, the article Mr. Trump shared was based on a fake Twitter account that posed as his sister.
That article, on the website of a conservative talk-radio host named Wayne Dupree, quoted a post from a Twitter account named “Betty Trump” that used a photo of Ms. Trump Grau as its profile picture.

Trump's stupidity is, well, stupefying.
