-- The 8-year-old girl who received a letter from President Obama after writing to him about Flint, Michigan, will get a chance to meet the commander-in-chief today.
The letter inspired the president to send Flint's mini-ambassador a letter of his own.
"You're right that Presidents are often busy, but the truth is, in America, there is no more important title than citizen," Obama wrote.
Obama wrote in his letter to Mari that he wanted her to be the "first to know" about his upcoming trip to Flint. "Like you, I'll use my voice to call for change and help lift up your community," the president wrote.
The meeting will take place this afternoon at Northwestern High School, where Obama will deliver remarks to a crowd of about 1,000 people, the White House told ABC News.
"In the end, it was my 8-year-old who convinced him that maybe it was time to come," Brezzell said, describing her daughter as a "force of nature" who "loves to use her voice"
Mari told ABC News that meeting the president will be better than her birthday and Christmas and is the "most exciting thing to happen" to her.
"People need him to give us hope," she said of Obama, adding that the first thing she'll do is "give him a big hug."
Mari received the title "Little Miss Flint" last spring after winning a local pageant, Brezzell said. Although her reign is almost over, another pageant system has offered to let her keep the title for another year because of all the awareness she's raised with it, Brezzell added.
In addition, Mari said education is an important issue to her. She enjoys cheerleading, gymnastics, tap dancing, singing and playing the violin, she said, and plans to "keep on helping" her fellow Flint residents.
"Cause I'm a kid that cares," Mari said. "We do not drink [the water] 'cause it's poison."
Brezzell said her family is not able to cook or bathe with the water that comes out of their faucet, saying they get rashes similar to chemical burns when it touches their skin. The mother of three called Flint's water crisis "heartbreaking" and "avoidable."
Mari's final message: "Don't forget Flint."
“We are hopeful the president will drink the water in Flint, to help reinforce Gov. Snyder’s actions and the EPA’s message that filtered Flint water is safe to drink,” Snyder spokeswoman Anna Heaton said in a statement to ABC.
In January, Obama addressed the water crisis in a visit to Detroit, saying he would be "beside" himself if his kids' health could be at risk. He declared a national emergency in Flint, directing funds to assist in relief efforts, following a request from Gov. Snyder.
It is unclear if the governor will meet will meet with the president during his visit. Snyder is not currently scheduled to be in Flint, according to his office.
