First Lady Melania Trump made history at a White House ceremony for signing a bill on Monday, where she attended with her husband, President Donald Trump.

The first lady affixed her signature to a piece of legislation she championed in an unprecedented move. The new Take It Down Act adds new protections against revenge porn and it was her first major legislative success.

First ladies signing bills into law along with their presidential husbands is highly unusual, DailyMail.com noted. But after she lobbied hard for the bill and met with lawmakers on Capitol Hill, the president thought it would be a nice touch to add her signature to his.

“Honey, you’ve done amazing,” the president said during the Rose Garden event. He added that when he first heard of the legislation, “I said, it sounds like a tough one, and yet a very important one, and you got it done. So I congratulate you.”

Trump noted that he had spoken to Russian President Vladimir Putin earlier in the morning. “Putin just said they respect your wife a lot. I said, ‘What about me?’ They like Melania better,”

Melania also spoke at the event in what was a rare White House appearance for her. She called the legislation a “national victory that will help parents and families protect children from online exploitation.”
