President’s decision to ban three news organisations from White House prompts backlash. Plus, a new resource to help trace the history of enslaved people in the 19th century

Good morning. The row over media access to the presidency has deepened, with major US television news outlets agreeing to suspend their video coverage of Donald Trump after the administration banned journalists from several outlets from entering the White House grounds.

The president had abruptly announced his ban against CNN, MS Now and Politico, saying he had had enough of “purposely negative stories” about him. On Monday the ban against CNN meant no broadcaster was covering Trump’s midday ribbon-cutting for a new White House helipad. The White House provided its own livestream but the president’s remarks were inaudible over the sound of a helicopter’s engine.

How have CNN, MS Now and Politico responded to the ban? A lawsuit seeks a temporary restraining order that would immediately lift the ban. In a statement, the organizations said: “We are filing a lawsuit today to protect our first amendment rights and defend the principle that the government does not decide what the press reports or publishes.”

What other significant media developments have there been? Paramount has reached a settlement with California and several other states that sued over its proposed $81bn merger with Warner Bros Discovery (WBD), the California attorney general announced, clearing the way to consolidate some of Hollywood’s most recognizable TV networks and studios under one owner.

What else is Trump expected to say at the UN? The US ambassador to the UN said Trump would speak about how he had “confronted complex problems head-on around the world”. Our writer Robert Tait notes in this analysis, however, that thanks to Trump’s recent social media blitz and self-proclaimed “25 top achievements”, the chances of an uplifting speech appear slim.
