LONDON (AP) — The BBC has issued a public apology to President Donald Trump over a misleading edit of his speech on Jan. 6, 2021, but said it “strongly disagreed there is a basis for a defamation claim.”

Over the past week, the BBC’s director general stepped down, its head of news quit, and Trump says he’s poised to file a billion-dollar lawsuit.

“We’ll sue them for anywhere between a billion and $5 billion, probably sometime next week,” Trump said.

Pressure on the broadcaster has been growing since the right-leaning Daily Telegraph newspaper published parts of a dossier compiled by the BBC’s adviser on standards and guidelines on Nov. 3. It showed how a third-party production company spliced together three Trump quotes from two sections of the Jan. 6, 2021, speech into what appeared to be one quote.
