Secretary of State Marco Rubio and tech billionaire Elon Musk have had a contentious exchange with Polish Foreign Minister Radoslaw Sikorski, in a series of X posts on Sunday over the use of Musk's Starlink satellite system in Ukraine.

The New York Times claimed in an article Friday that Musk, while at closed-doors cabinet meeting, accused Rubio of refusing to slash his staff, following weeks of DOGE making a dizzying array of cuts to federal personnel and programs.
