BBC:-Donald Trump’s former presidential campaign manager, Paul Manafort, has been charged with conspiring to defraud the US in his dealings with Ukraine.
The 12 charges brought against Mr Manafort and one of his business associates, Rick Gates, include conspiracy to launder money.
They stem from an inquiry into alleged Russian meddling in the US election.
It has emerged that another adviser to Mr Trump admitted this month to lying about his links to Russia.
George Papadopoulos pleaded guilty to making false statements to FBI agents about his dealings with an unnamed overseas academic who allegedly informed him that the Russians possessed “dirt” on Mr Trump’s presidential opponent, Hillary Clinton.
The charges against Mr Manafort and Mr Gates do not relate to Mr Trump’s campaign but to the alleged concealment of payments from the pair’s Ukrainian business dealings up to 2016.
An investigation headed by special counsel Robert Mueller is looking into any links between Russia and the Trump campaign. Both sides deny any collusion.
Responding to news of the charges, Mr Trump tweeted to point out that they did not concern his campaign and asked why “the focus” was not on alleged wrongdoing involving Mrs Clinton instead.
