Donald Trump released a furious tirade Friday over coverage of his trade tariffs on MSNBC.

The network is a frequent target for Trump, who has claimed it’s a liberal outlet that works in partnership with the Democratic Party. He calls it MSDNC.

Though he doesn’t refer to it directly, his Friday fury followed a Thursday night segment in which host Lawrence O’Donnell called Trump an “illiterate clown” and “a rogue president violating American law on tariffs.”
