Rosenworcel was first nominated to the FCC by President
Barack Obama in October 2011. On July 13, 2012,
Politico designated Rosenworcel as one of 50 politicos to watch, describing her as "whip-smart and intensely serious". By law, commissioners may continue serving until the appointment of their replacements, but not beyond the end of the next session of Congress following term expiration. In May 2015, President Obama renominated Rosenworcel for a second term, but she was not reconfirmed by the Senate by the time she was required to leave her seat in January 2017. In June 2017, Rosenworcel was nominated to an additional term by President
Donald Trump. She was confirmed by the Senate on August 3, 2017. Following the election of
Joe Biden as president, Biden named Rosenworcel as his choice to become chairperson of the FCC after the departure of prior chairman
Ajit Pai with the change in administration. Biden named Rosenworcel to serve as acting chairwoman in the interim, making her the second-ever woman to serve in this position. Biden later named Rosenworcel to be the permanent FCC Chairwoman in October 2021, making her the first female to hold the permanent chairperson position on the FCC, and she was confirmed by the Senate on December 7, 2021, for another term as commissioner. She resigned from the FCC in January 2025. Rosenworcel served as the Chairwoman of the
Federal-State Joint Conference on Advanced Telecommunications Services, a forum for dialogue among the FCC, state regulators, and local and regional entities about the deployment of advanced
telecommunications capabilities. In 2022, Rosenworcel announced new plans to create a space bureau within the FCC to address the increased number of satellite launches.
Positions During her initial term as an FCC commissioner, Rosenworcel voted to enforce
net neutrality by classifying
Internet service providers as Title II common carriers, overturn state laws that protect Internet service providers against competition from
municipal broadband, change the technical definition of "broadband" from 4 Mbit/s to 25 Mbit/s, use the
LifeLine program to subsidize Internet access for low-income individuals, and expand consumer protection against
robocalls. On the latter topic, Rosenworcel in 2019 argued that the FCC should order telecommunications companies to provide free call-blocking services. On March 17, 2021, she kicked off an anti-robocall agenda. This agenda includes issuing significant fines to companies, demanding cease-and-desist, and launching a Robocall Response Team. On
net neutrality, Rosenworcel said, "We cannot have a two-tiered Internet with fast lanes that speed the traffic of the privileged and leave the rest of us lagging behind. We cannot have gatekeepers who tell us what we can and cannot do and where we can and cannot go online, and we do not need blocking, throttling, or paid prioritization schemes that undermine the Internet as we know it." In addition, Rosenworcel is responsible for coining the term "
homework gap", and has brought attention to the need of students to get online when they are outside of school. Rosenworcel supports proposals to improve communications infrastructure and location accuracy for 911 calls from
cell phones, and supports the expansion of
FirstNet, a dedicated wireless network for
emergency services workers. == Post-FCC career ==
