Meredith Attwell Baker's announcement that she would leave the Federal Communications Commission (FCC) to join Comcast raised a storm of controversies.

Californian Republican Darrell Issa, who is also the chairman of the US House Committee on Oversight and Government Reform, asked the FCC to explain Baker’s departure to Comcast, just four months after she voted to in favor of the cable company’s NBC Universal deal.

In a letter written to the FCC, Issa asked what actions Baker took to make sure compliance with rules that govern employees’ departure.

Critics say Baker tailored her vote on the merger with an eye toward joining Comcast.

Policy director Andrew Schwartzman, of the Media Access Project in Washington, said the system is “fundamentally flawed.”

Speaking on topic, Schwartzman said, “People attain expertise which is extremely valuable to the regulated companies and turn around and make that expertise available to them at the expense of the public."

Before joining the FCC in 2009, Baker served as a Commerce Department executive under President George W. Bush. She has plant to leave the FCC on June 3 to join Comcast’s NBC Universal as the chief of government relations.
