According to the Biden administration on Friday, US Pentagon Press Secretary John Kirby will join the National Security Council as the coordinator for strategic communications.

The National Security Council advises the President of the United States on international policy.

A White House statement detailed how Kirby's new responsibility would be to "coordinate interagency efforts to explain United States policy and (serve) as a senior administration voice on related matters." 

According to the detailed statement by President Joe Biden, "John understands the complexities of US foreign and defense policy, and he will ably represent the Administration on important national security issues."

Kirby has worked in the Pentagon and the US State Department, most notably as the latter's spokesperson under the Obama administration. 

During Donald Trump's administration, he served as a CNN military and diplomatic affairs commentator.

Kirby will report to US National Security Adviser Jake Sullivan, the release said.
