She also served in the National Telecommunications and Information Administration as a political appointee, and was subsequently named a deputy assistant secretary of the Commerce Department by President George W. Bush in February 2007.

[1] From 1998 to 2000, Baker served as director of congressional affairs for CTIA,[1] at which she helped designate 9-1-1 as the national emergency number and fought against cell phone "cloning".

[3] She then served as senior counsel at Covad Communications from 2000 to 2002,[3][1][4] taking time off to assist George W. Bush's campaign with the 2000 United States presidential election recount in Florida.

[1][4] In January 2004, Baker joined the National Telecommunications and Information Administration (NTIA), which is an agency of the United States Department of Commerce, as a senior advisor.

[1] During her tenure at NTIA, Baker "advised and represented the Executive Branch on both domestic and international telecommunications and information policy activities".

[3] In 2008, Baker voiced concern over the FCC's ruling that Comcast violated policy by "blocking and degrading" file-sharing applications.

[2] Baker reportedly voted "with some reservations" to start creating new net neutrality guidelines only after voicing her concerns to Julius Genachowski.

[7][8][10][11] The company said that it did not approach Baker about the position until mid April, after NBC Universal lobbyist Bob Okum resigned.

Comcast also noted that Kyle E. McSlarrow, who hired Baker at NBC Universal, was not employed by the company when the merger was completed; he was serving at the National Cable and Telecommunications Association (NCTA) at the time.

[11][12] Baker became CTIA's president and CEO in mid 2014,[15][16] having previously served as the advocacy group's director of congressional affairs from 1998 to 2000.
