The honeymoon period has begun for Jessica Rosenworcel and Ajit Pai, who’ll be sworn in as FCC commissioners this week following their confirmation today by the U.S. Senate. President Obama nominated the two in November, but Sen. Charles Grassley (R-Iowa) blocked confirmation while he investigated the FCC’s decision early last year to give LightSquared permission to become a national wireless network — before tests revealed that it could interfere with military GPS systems. Rosenworcel, a Democrat who replaces Michael Copps, was Senior Communications Counsel for the Senate Committee on Commerce, Science, and Transportation. Pai, a Republican, replaces Meredith Baker — who left to work for Comcast — and was the FCC’s deputy general counsel. FCC chairman Julius Genachowski says the two “bring deep knowledge of our sector, and proven track records of accomplishment” to the five-member commission. Congratulations also poured in from business and consumer groups. The National Association of Broadcasters called them “well-respected public servants.” The trade group’s frequent opponent, Public Knowledge, says the new commissioners are “extremely knowledgeable policy experts.” And cultural watchdog group Parents Television Council praised the duo’s “years of experience inside and outside the agency.”
