New York: Ajit Pai, one of the senior-most Indian-American officials appointed by US President Donald Trump, announced that he was quitting the Chairmanship of the Federal Communications Commission (FCC) on January 20, when Joe Biden takes over as President.
He also campaigned for other democracies to shut out those companies.
Pai said in the statement about leaving office that he was proud of "aggressively protecting our communications networks from national security threats at home and abroad".
The Chairmanship of the FCC is one of the most powerful jobs in the US because the federal authority regulates the cellphone spectrum and services, phone, internet and satellite and cable services.
Its powers even extend to setting and enforcing certain content norms like obscenity in TV and radio and conditions like the amount of local news content stations must carry.

"To be the first Asian-American to chair the FCC has been a particular privilege. As I often say: only in America," he said.
Another senior Trump appointee at just below the cabinet-level, Seema Verma who heads the Centers for Medicare and Medicaid Services, the agency for government health insurance programmes, and is a key member of the White House Coronavirus Task Force is also expected to quit when Biden becomes President.
What drew the most attention during Pai's tenure was his controversial plan to end net neutrality, a decision that faced strong opposition from many and played into the national polarisation to the extent of getting death threats against his children.
Net neutrality prevented internet service providers from giving special preferences to certain web sites or priority or better access to web sites in exchange for payment.
