Trump and his sons, Donald Trump, Jr., and Eric Trump, were detained in November 2016 on an international flight from London to New York City.
They had been travelling together for several weeks and had returned to the US.
When the United States attorney’s office in Manhattan said it could not file charges against them, the case moved to a federal court in Manhattan, where a jury would decide whether they were criminally liable for their alleged crimes.
The Trump and Trump Jrs were charged with conspiring to commit financial fraud, conspiracy to commit mail and wire fraud, and conspiracy to launder money.
The charge of conspiracy to violate the Espionage Act of 1917, the Espyionage Act, and aiding and abetting a foreign power were also added.
Prosecutors argued that the Trump and the Trump Jr’s had violated the Espen- stitution by using the Trump name and the name of his brother-in-law, Donald J. Trump, to promote his business.
The case has become a flashpoint in US relations with Russia and has caused deep divisions between the two countries.
The defendants are scheduled to be sentenced on Tuesday.
Trump Jr. has said that the meeting with the Russian lawyer was not about the election.
Trump and son Eric have denied having anything to do with the meeting.
In the days before the trial, Trump Jr released a series of emails, in which he discussed whether he would testify in a Russian-related lawsuit against him and his father.
In one email, he wrote: If I do testify, I want to make sure that it is absolutely true, and I will provide absolutely nothing that could be construed as a statement that my father had anything to say in any way about the campaign, the election or any of the other things in that email.
But if I don’t, I will be the victim of a witch hunt.
The charges against the Trump family were later dropped.
A judge said at the trial that he would impose an additional $500,000 fine on the Trump administration for its role in the case.
Trump’s lawyers also called the prosecution “sham” and said that prosecutors had presented a “lack of credibility”.
In response to a letter from the US attorney’s offices in New York and Brooklyn, Eric Trump said: This trial is a sham and a sham judge.
The judge has no jurisdiction.
The attorney for the Trump campaign, Marc Kasowitz, responded by saying that the trial had been “worse than a circus”.
The Trump administration has called the case “unconscionable” and the “worst example of an unprofessional and unethical prosecution”.
