Rosenworcel, who has served on the FCC since 2012, said it is "a privilege to serve the American people and work on their behalf to expand the reach of communications opportunity in the digital age."
She's a frontrunner to be chosen as the FCC's permanent chair, but she faces competition from some outside contenders who are close to President Biden, including former FCC Commissioner Mignon Clyburn.
She told Protocol during an interview last year that she believes the FCC's top priority should be getting "100% of households online."
"It needs to be a national policy — 100%, nothing less, because everyone needs to have access to affordable and reliable broadband," Rosenworcel said. "Without it, every other goal we have in the next few years is going to be difficult to reach. And there's no individual, household, business or community that will have a fair shot at success in the digital age without it."
