The role of Donald Trump’s national security adviser role has been filled by a variety of faces over the years, some lasting longer than others.
Let’s look back at who they were:

The man of the hour. He will be temporarily replaced by Marco Rubio.
Robert O’Brien – 1 year, 124 days
O’Brien was hired by the Trump administration in September 2019 and stayed until the end of his first term in 2021.
Charles Kupperman – 8 days
Kupperman took over for a short stint after his predecessor John Bolton left the post after clashing with Trump.

Bolton was Trump’s longest serving national security adviser, but the two had major foreign policy disagreements.
“I asked John for his resignation, which was given to me this morning,” Trump tweeted in September 2019.
HR McMaster – 1 year, 48 days
A former army general, McMaster was another adviser that did not get along with Trump.
Trump had referred to the army lieutenant general’s briefings as “gruff and condescending”, a source told CNN.
Keith Kellogg – 7 days
Like Kupperman, Keith Kellog was the interim adviser after Trump sacked Michael Flynn.

On the job for just under a month, Flynn resigned in February 2017 over allegations of collusion with Russia before Trump took office.
