Two Trump donors have been charged with violations of campaign finance laws, New York prosecutors say.

Soviet-born businessmen Lev Parnas and Igor Fruman conspired to “funnel foreign money to candidates for federal and state office”, say the charges.

The pair have been associated with US President Donald Trump’s personal lawyer Rudy Giuliani.

They have been peddling unsubstantiated corruption claims against a top Democratic presidential contender.

Both men are US citizens. Mr Parnas was born in Ukraine, Mr Fruman in Belarus.

The two men were arrested at Dulles International Airport in Virginia before they could board a scheduled flight to Vienna, Austria, on Wednesday night.

They appeared in federal court in Virginia on Thursday.
