A lawyer for Donald Trump told a London judge Monday the ex-president plans to prove that “shocking and scandalous claims” about him in a largely discredited report by a former British spy were false and harmed his reputation.

Trump has sued the company founded by Christopher Steele, who created a dossier in 2016 that contained rumors and uncorroborated allegations about Trump that erupted in a political storm just before he was inaugurated. Trump is seeking damages from Orbis Business Intelligence for allegedly violating British data protection laws.

Steele’s firm is seeking to have the case thrown out and a judge said she would rule at a later date after hearing arguments in London’s High Court.

The lawsuit comes as Trump is the front-runner for the 2024 Republican presidential nomination while facing legal problems on the other side of the Atlantic.
