On Saturday night, the daughter of New York City Mayor Bill de Blasio was arrested during a protest over the death of George Floyd. Now, de Blasio is speaking out to say that he is “so proud” of his daughter for taking her protest far enough that it landed her behind bars.

During a press conference on Monday, de Blasio said that neither he nor his wife Chirlane McCray knew that their 25-year-old daughter Chiara had the “intention to get arrested,” adding that he was fully supportive of what she did when he heard the news.

“I love my daughter deeply. I honor her. She is such a good human being. She only wants to do good in the world. She wants to see a better and more peaceful world,” de Blasio said. “I’m proud of her that she cares so much she was willing to go out there and do something about it.”

Chiara was arrested hours after de Blasio blamed President Donald Trump for the violent unrest in his city. “I can tell you this, and this is the blunt truth, the president of the United States helped to create this atmosphere, and that’s the tragedy here,” de Blasio claimed earlier on Saturday. “It doesn’t matter what your party affiliation is, doesn’t matter what you think of President Trump, there’s been an uptick in tension and hatred and division since he came along. It’s just a fact.”

Chiara was arrested at around 10:30 p.m. Saturday night for blocking traffic on Broadway, known for being one of the busiest streets in New York City, to protest the death of George Floyd earlier in the week. She was taken into custody while she was with a large group who had been antagonizing NYPD officers and throwing things at them, although sources told the New York Daily News that Chiara did not actually throw anything herself.

“She was acting peacefully,” de Blasio said on Monday. “She believes everything she did was in the spirit of peaceful, respectful protest. I admire that she was out there trying to change something she thought was unjust and trying to do something in a peaceful manner.”
