Elon Musk, escalating his battle with media companies, suggested he may strip NPR of its Twitter handle because it had stopped tweeting.

The billionaire said in a series of emails Tuesday he may transfer the @npr handle — which has remained dormant for weeks — to “another company,” NPR reported. 

NPR quit Twitter last month after Musk stirred controversy by labeling its account “state-affiliated media,” along with those for the BBC, PBS and other publicly funded organizations.
