A 9-year-old girl from Massachusetts just heard back from the president regarding her request to get more women on U.S. currency.
Sofia sent a letter to President Barack Obama last summer wanting "to know why there aren't many woman [sic] on the dollars/coins for the United States," according to a copy of the letter provided to Time Magazine.
"I think there should be more woman on a dollar/coin for the United States because if there were no woman there wouldn't be men," she wrote, adding that there are many women that deserve to be featured on U.S. currency because of the "important things" they've done.
Included on her list of suggestions were Rosa Parks, Betsy Ross, Abigail Adams and First Lady Michelle Obama.
Sofia told Time she "sort of forgot about" her letter when months passed without any response from the president. But in February, she received a letter from the White House.
"This is a belated note to thank you for writing to me with such a good idea last summer. The women you listed and drew make up an impressive group, and I must say you're pretty impressive too," the president wrote, according to a copy of the letter obtained by Time.
"I'll keep working to make sure you grow up in a country where women have the same opportunities as men, and I hope you'll stay involved in issues that matter to you," Obama wrote.
In the months since Sofia sent her letter to the White House, a nonprofit campaign called "Women on 20s" launched with the goal of getting the face of a woman on the $20 bill by the year 2020. The group mocked up images of $20 bills featuring Sojourner Truth, Eleanor Roosevelt and others -- including several that were on Sofia's list of suggestions.
