June 27 (Reuters) - The chair of the Federal

Communications Commission asked the CEOs of AT&T ( T ), Verizon

, Comcast ( CMCSA ) and other cable and telecom carriers

to detail efforts to crack down on fraudulent AI-generated

political robocalls, the agency said Thursday.

Last month Steven Kramer, a Louisiana Democratic political

consultant, was indicted over a fake robocall imitating U.S.

President Joe Biden seeking to dissuade people from voting for

him in New Hampshire's Democratic primary election. The FCC in

May proposed to fine Kramer $6 million over the robocalls it

said were using an AI-generated deepfake audio recording of

Biden's cloned voice, saying its rules prohibit transmission of

inaccurate caller ID information. Kramer has pleaded not guilty.
