    The mayor of Flint offered Miss Michigan Emily Sioma high praise on Tuesday for speaking out at this weekend's Miss America conference about the city's water crisis.

“I was really excited for her to do that," Mayor Karen Weaver told TMZ. “I think she was very brave because so many times you say who you are and where you're from and just general information. For her to take that opportunity and use her platform and use her voice to speak up about what‘s going on in Michigan and in Flint, in particular, was just amazing. ”

Emily Sioma,24,introduced herself on stage on Sunday by saying,“From the state with 84 percent of the U. S. fresh water but none for its residents to drink. I am Miss Michigan Emily Sioma.” The brief ‘speech was a reference to Flint, a town with lead-filled drinking water.

Weaver said Sioma's decision to speak about the Flint water crisis demonstrated her impressive character. “I applaud her for being a brave young woman. And it also shows you that she’s not a selfish person," Weaver said. “She could have talked only about herself, but she chose to use this opportunity to bring attention to, and keep attention on, what’s going on in Flint, what’s going on with water quality standards what's going on with this broken infrastructure(基础设施) that we have across the country. "

Ratings showed that 4. 3 million viewers watched the ABC program. Although Miss New York Nia Imani Franklin ultimately won the competition, many Twitter users quickly got behind Sioma, who did not make the final 15, after her introduction.

“Emily Sioma wanted to make an impact,” one Twitter user wrote on Sunday. Regardless of whether you agree with what she said or not- she is shining light on a pressing issue that we have in our state and that is still not solved. That, is a Miss America."
