President Donald Trump stepped up his onslaught on federal Special Counsel Robert Mueller's probe into Russia and the 2016 U.S. election on Tuesday, saying that his campaign did not collude with Moscow but that collusion is not a crime anyway.
Trump launched his new attack hours before his former campaign chairman, Paul Manafort, was due to go on trial on tax and bank fraud charges in Virginia. As the first trial in the 14-month Russia probe, the case throws a fresh spotlight on an investigation that has dogged Trump's presidency.

Mueller is investigating whether Trump campaign officials worked with Moscow to try to sway the 2016 U.S. presidential election, something commonly referred to as collusion by the media and public officials.
"Collusion is not a crime, but that doesn't matter because there was No Collusion (except by Crooked Hillary and the Democrats)!" Trump wrote on Twitter.
Collusion is not a crime, but that doesn’t matter because there was No Collusion (except by Crooked Hillary and the Democrats)!
While collusion is not a technical legal charge, Mueller is probing any coordination between the Russian government and the Trump campaign, and could bring conspiracy charges if he finds that any campaign member worked with Russia to break U.S. law.
Trump has denied any collusion for months. On Tuesday, he echoed his personal lawyer, Rudy Giuliani, who said in television interviews on Monday that collusion is not a crime. The strategy may be the latest in Trump's efforts to strip legitimacy from the Mueller probe, which he has long denounced as a "witch hunt."

Legal experts said that working with a foreign national with the intent of influencing a U.S. election could violate multiple laws.
A campaign finance law makes it a crime to solicit a "contribution or donation of money or other thing of value" from a foreign national in connection with an election, which could include opposition research.
"Collusion is basically a partnership in crime, which is conspiracy," said Randall Eliason, a former federal prosecutor and a law professor at George Washington University.
Trump has denied that the campaign worked with Russia to try to engineer his victory against Democratic candidate Hillary Clinton and bristles at the suggestion he might owe his White House victory to Moscow.
Russia has denied the finding of U.S. intelligence agencies last year that it interfered to sway the election to Trump.
Paul Manafort on Tuesday will become the first of President Donald Trump's former aides to go on trial, accused of bank and tax fraud by federal investigators probing Russian meddling in the 2016 U.S. presidential election.Despite a focus on financial crimes, the trial could yield politically damaging headlines about a man who ran Trump's campaign for three months and attended a June 2016 meeting with Russians offering damaging information about Trump's Democratic rival Hillary Clinton that is now a focal point of Special Counsel Robert Mueller's 14-month-old probe."My guess is you will see O.J.-type frenzy at this court event," said Michael Caputo, a former Trump aide and longtime Manafort associate, referring to the 1995 O.J. Simpson murder case. "I really hope the president continues to watch and make public comments about this case."Trump accuses Twitter of targeting Republicans, offers no evidenceHe said Trump could help the public understand what is at stake in Mueller's probe, which both Trump and Caputo have called a "witch hunt" aimed at ending his presidency.Prosecutors are expected to argue that Manafort's lavish spending on suits, homes and luxury items did not match the income declared on his tax returns and that he misled lenders when he borrowed tens of millions of dollars against New York real estate.Joshua Dressler, a law professor at Ohio State University, said the evidence against Manafort, 69, appears strong, but that he drew a favorable judge in the 78-year old T.S. Ellis, who is known to be tough on prosecutors, and said the politically charged climate increases the chances of a hung jury.Russia preparing for meeting with US security advisorManafort, who has pleaded not guilty, faces 18 counts. The nine bank fraud and conspiracy charges alone carry maximum sentences of 30 years each, and Judge Ellis noted in April that Manafort was potentially facing the rest of his life behind bars.Given the strength of the evidence, however, some legal experts have suggested Manafort may be banking on an eventual pardon from Trump, who has called his former campaign chairman a "nice guy" who has been treated unfairly.The trial, starting with selection of a 12-member jury, coincides with growing speculation that Trump's former personal lawyer Michael Cohen may cooperate with federal investigators against the president, now 18 months in office.Trump seeks to revive 'Arab NATO' to confront IranMueller's team has estimated it could take 8 to 10 days to present its case to the jury, suggesting the trial may last at least three weeks.A TRUMP PARDON?Mueller submitted 500 pieces of evidence, including tax filings and mortgage statements, and pictures of luxury watches and homes to illustrate Manafort's wealth. There are 35 potential witnesses, many of them bankers and accountants expected to verify documents and speak to Manafort's alleged intent to violate the law. Five witnesses were granted immunity.Rudy Giuliani, a lawyer for Trump, said no one facing trial should proceed expecting a pardon, but he did not rule one out. Giuliani said he and Jay Sekulow, another Trump lawyer, had told the president: "This would be a very bad thing to do now."But once Mueller's Russia investigation ends, Giuliani told Reuters, “he has a right to consider it ... It’s his power.”Mueller's team said it would not present evidence about any possible campaign collusion with Russia at the trial in the Washington suburb of Alexandria, Virginia, potentially saving it for a second Manafort trial in Washington in September.Even so, prosecutors have asked permission to discuss Manafort's work for pro-Russia politicians in Ukraine, which they allege was a source of wealth he laundered through overseas bank accounts. Manafort is seeking to exclude information on the details of that work. The judge has yet to rule.RUSSIAN CONNECTIONS?If allowed, prosecutors may delve deeper into Manafort's Russian connections. Last month Mueller's team disclosed in a court filing what it said was a $10 million loan to Manafort from Oleg Deripaska, a magnate known to have close ties to Russian President Vladimir Putin."It seems to me we’re seeing deeper ties that Manafort has had financially with his business deals in the Ukraine and with Russia," said Shanlon Wu, a former lawyer for Manafort associate Rick Gates, who pleaded guilty in February and is aiding Mueller's probe. "He could expose himself to further criminal culpability if he has to expose the full extent of those ties."One transaction set to take center stage is an alleged quid pro quo arrangement between Manafort and a senior executive at the Federal Savings Bank, which public records show lent Manafort $16 million against New York properties in December 2016 and January 2017.Prosecutors say the loans were a favor for Manafort bringing the executive, who sources say is Federal CEO Stephen Calk, into Trump's inner circle. Calk was named an adviser to the Trump campaign, and Democratic lawmakers say he inquired about, but did not get, a key Army post.Federal did not respond to a request for comment.Expected to be a key witness, Gates was Manafort's right-hand man for years and has knowledge of their offshore accounts and work for Deripaska and in Ukraine."Gates is going to be the narrator for this entire trial," said Dan Goldman, a former federal prosecutor in New York.Mueller's team has indicted or secured guilty pleas from 32 people and three companies, including the indictment of 12 Russian intelligence officials. Of the four former Trump aides ensnared by the probe, Manafort is the only one to go to trial.Gates, former national security adviser Michael Flynn and George Papadopoulos, a foreign policy adviser on the campaign, have all pleaded guilty.Trump denies any collusion. But Trump and his aides have struggled to control the damage from his acceptance at times of Putin’s denials that Russia interfered over the word of American intelligence agencies that it did.Trump threatens US government shutdown over immigrationTrump says did not know of 2016 Trump Tower meeting with Russians

"As a matter of law, the central question is not whether members of the Trump campaign coordinated or colluded with Russia, but whether they conspired with Russians to break a criminal statute or they broke the law themselves," the Council of Foreign Relations wrote in a background paper.
That could include hacking into Democratic Party computers, it said. "'Collusion' and 'coordination' are not legally relevant terms, but they are often used as shorthand to refer to such a criminal conspiracy," it said.
Manafort, 69, faces 18 criminal counts, which center on allegations that he hid much of the $60 million he earned working for a pro-Russian politician in Ukraine in undisclosed overseas bank accounts and failed to pay taxes on it.
A Manafort conviction would give momentum to Mueller, who has indicted or secured guilty pleas from 32 people and three companies since the probe started 14 months ago.
