Charles Kupperman, US Deputy National Security Advisor, will replace John Bolton, as reported Reuters.

Kupperman, 68, has held administrative positions for Lockheed Martin and Boeing. In the 1980s, he was part of US President Ronald Reagan’s administration, and in 2001-10, he was a member of the Board of Directors of the US Center for Security Policy.

Kupperman became Bolton’s deputy in January 2019.
