A co-founder of the Congressional Cybersecurity Caucus rebuked National Security Advisor John Bolton on Tuesday for eliminating the White House cyber coordinator position.
The news was first reported by Politico.
Detractors say the role was important symbolically, though, and perhaps structurally as well - Senator Mark Werner (D-VA) says the coordinator was "the only person in the federal government tasked with delivering a coordinated, whole-of-government response to the growing cyber threats facing our nation". The NSC's cyber team has two senior directors, the email said, and thus "cyber coordination is already a core capability".
"Today's actions continue an effort to empower National Security Council senior directors".

The Trump administration has eliminated the White House's top cyber policy role, Politico reports.
