UPDATE 3:00 PM EDT -- 
The "Mr. Browder" referenced by President Putin at the Helsinki Press conference refers to William Browder, the Chief Executive Officer of Hermitage Capital Management, an investment fund that at one time was the largest foreign portfolio investor in Russia.

He gave up his U.S. citizenship in 1998 to avoid paying taxes related to foreign investment.  (Hal Turner Note: Non-U.S. Citizens cannot make __any__ financial contributions to __any__ candidate for American federal political office. So if President Putin is telling the truth, that Browder gave $400 Million to the Hillary Clinton Campaign, then this man seems to have committed severe federal felonies. Browder is now a citizen of . . .  Britain.  You know, where the "Trump pee-pee Dossier" was authored!)  
After having business in Russia for ten years, Browder was refused entry to Russia in 2005 as a threat to national security; he has said it was because he exposed corruption.
After the death in prison in 2009 of Sergei Magnitsky, a Russian lawyer and auditor who had represented his company and conducted an investigation into massive tax fraud related to it, Browder lobbied for Congress to pass the "Magnitsky Act", a law to punish Russian human rights violators, which was signed into law in 2012 by President Barack Obama.
In 2013, Browder was tried in absentia in Russia for tax fraud, jointly in a posthumous prosecution of Magnitsky. He was convicted and sentenced to nine years in prison. 

Interpol rejected Russian requests to arrest Browder, saying the case was political.
In 2014, the European Parliament voted for sanctions against 30 Russians believed complicit in the Magnitsky case; this was the first time it had taken such action.
In July 2017, Browder testified to the U.S. Senate Judiciary Committee on Russia's alleged interference in the 2016 U.S. presidential election through use of persons in Washington, D.C. (Hal Turner Note: Interesting that this man, William Browder, who now appears to have illegally given $400 million to Hillary, happens to be the man testifying to the US Senate about "Russia Collusion" with Trump.  What it is starting to look like is that this Billionaire, Browder, is a central figure in the scurrilous and fraudulent accusations against President Trump BECAUSE Browder wants to conceal and deflect attention from his illegal contribution to Hillary!)
On October 21, 2017, as part of a criminal conviction for tax evasion, the Russian government attempted to place Browder on Interpol's arrest list. After a protest by U.S. Congressional leaders, his visa was restored the following day. Russia's arrest-warrant request was rejected by Interpol on October 26, 2017.  (Hal Turner Note: US Congressional leaders?   Who perhaps also get contributions from Billionaire Browder??? The plot thickens.  Looks like Congress is "in on it" too!)
While visiting Spain in May 2018, Browder was arrested on 30 May 2018 by Spanish authorities on a new Russian Interpol warrant and transferred to an undisclosed Spanish police station, yet he was released two hours later, after Interpol confirmed that this was a political case.
William Felix Browder was born into a Jєωιѕн family in Chicago, Illinois. He attended the University of Colorado, Boulder before transferring to the University of Chicago, from which he graduated with a degree in economics. He earned an MBA from Stanford Business School in 1989 and entered the financial sector.   (Hal Turner Note:  Chicago.  Home of Barack Obama; gee another coincidence.)
FULL COMMUNIST BACKGROUND!
Browder's paternal grandfather was Earl Browder, who was born in Kansas in 1891. He was a radical and had lived in the Soviet Union for several years from 1927 and married Raisa Berkman, a Jєωιѕн Russian woman, while living there. After his return to the United States in 1931, Earl Browder became the leader of the Communist Party USA, and ran for U.S. president in 1936 and 1940. After World War II, Earl Browder lost favor with Moscow and was expelled from the American Communist party.
Earl and his wife Raisa had three children, all sons, and all three became mathematicians who headed the mathematics departments of top American universities including Bill Browder's father Felix Browder who married Eva (Tislowitz). Felix was a mathematics prodigy who had entered MIT at 16, acquired his bachelor's degree in two years, and by the age of 20 had a Ph.D. from Princeton. 
But during the McCarthy era, he could not find work because he was the son of the onetime head of the Communist Party USA. After a series of job rejections in the 1950s, he was championed by Eleanor Roosevelt, the former First Lady who was then chairman of the board of Brandeis University; she overrode the rest of the board who were afraid to hire him, and he gained a position at Brandeis. 
Felix went on to chair the mathematics department at the University of Chicago, and in 1999 became the president of the American Mathematical Society.
Felix Browder was renowned in the field of nonlinear functional analysis — a branch of mathematics with wide applications to such fields as physics, engineering, and finance. He was instrumental in establishing a science and technology center in conjunction with Princeton University and Bell Labs. In 1999, he was awarded the National Medal of Science by President Bill Clinton, for his "key role in the explosive growth of nonlinear functional analysis and its applications to partial differential equations in recent years".
Bill Browder has one sibling, Tom Browder, who entered the University of Chicago at 15, and became a leading particle physicist.
 
MOTIVE: REVENGE AGAINST PEOPLE OF USA
In 1998, Bill Browder gave up his U.S. citizenship and became a British citizen, partly to avoid paying U.S. taxes on foreign investments. At the time, he was working in the Eastern European practice of the Boston Consulting Group in London, and managed the Russian proprietary investments desk at Salomon Brothers.
In October 2017, when answering a question about the decision to renounce his U.S. citizenship, he cited "a legacy of bad feeling about the rule of law" as a result of his family having been "viciously persecuted" by the U.S. authorities in the 1950s. (Hal Turner Note: That, ladies and gentlemen, is, in my opinion, his "motive" -- he HATES the people of the United States for how his Communist Parents were treated and I think he wants REVENGE against America.  Revenge is a powerful motivation!)
