I have multiple plane crashes to deal with now, and your people want me to fire air traffic controllers? Mr. Musk told Mr. Duffy that his assertion was a 'lie.'

In a post on X on Friday, Mr. Duffy praised Mr. Trump and the work Mr. Musk’s team is doing and said it was an effective cabinet meeting....
