On the same day US President Donald Trump held a social media summit without inviting the two biggest social media companies Twitter and Facebook, the White House also reportedly held an in-house meeting on 5G policy.

The discussion was to "combat infighting" about the new mobile network technology, Axios reported Thursday afternoon.

5G, already launched in some parts of the US by Verizon, AT, Sprint and T-Mobile, is the next-generation network being used by smartphones to provide faster speeds and more capacity.

The "high-level" White House meeting was called by Mick Mulvaney, acting White House chief of staff, because "tensions over 5G have come to a head" in Trump's administration, according to Axios citing two administration officials.

The meeting was led by Larry Kudlow, director of Trump's National Economic Council, the report said, and included Ajit Pai, Federal Communications Commission (FCC) chair as well as officials from the Defense, State, Commerce and Education departments.

Mulvaney's office and the FCC didn't immediately respond to requests for comment.
