Trump reportedly will appoint the Republican from Florida to the position the name Green was mentioned for.

The war veteran in Afghanistan and a longtime supporter of Trump, Waltz was re-elected to Congress last week, but if his appointment is confirmed he will have to release his office to serve at the White House.

In this role, Waltz would serve as the White House's principal adviser to national security issues and foreign policy.

As reported during the day, Senator Marco Rubio from Florida is in talks to be Trump's nominated secretary of state, although choice is not a closed deal, the American media reported.

President of these two positions mentioned Richard Green.

Greenell, who has served as US ambassador to Germany and has exercised the duty of director of national intelligence, was mentioned in the past week as a possible name to serve at one of the previous two positions.

“He is considered president of Secretary of State or National Security Adviser”, the BBC reported last week.
