President-elect Donald Trump has tapped Rep. Mike Waltz of Florida to serve as his national security adviser, a source familiar said.

In that role, Waltz would have to deal with a number of geopolitical conflicts that Trump’s administration will take on as part of its second term, including the wars between Ukraine, Russia and Israel and Hamas.

The congressman had been seen in recent days in Palm Beach, home to Trump’s Mar-a-Lago resort.

This is a developing story and will be updated.
