Republican presidential candidate Sen. Marco Rubio, R-Fla., attacked Democratic candidate Hillary Clinton Wednesday over her ties to teachers unions.

"Hillary Clinton, who's probably going to be the Democratic nominee, is not going to be able to be an innovator on K-12 because she's fully owned by the teachers union when it comes to K-12 education," Rubio said in an interview with The 74's Founder Campbell Brown. "The Democratic Party relies heavily on contributions and support from teacher unions around the country, who, quite frankly, are one of the biggest impediments to educational reform in this country. And so [Clinton] is a captive of that. They've taken over the Democratic Party's educational agenda."

Clinton is endorsed by the two biggest teachers' unions in the country, the National Education Association and the American Federation of Teachers. Combined, the two unions have 4.8 million members.

Rubio pointed out that many Democrats have grown to be supporters of school choice, referencing his time in the Florida House of Representatives from 2000 to 2008. "We found, for example, a majority of the African American legislators that were Democrats began to become supporters of school choice."
