Answer the question at the end by quoting:

Andrew Jeremy Wakefield (born 1957) is a medical researcher and anti-vaccine activist. He worked as a gastroenterologist until he ultimately lost his accreditation from the UK medical register for allegations of unethical behaviour and fraud. In 1998 he authored a widely read research paper claiming that there was a link between the administration of the polyvalent measles, mumps and rubella (MMR) vaccine and the appearance of autism and bowel disease. After the publication of the paper, other researchers were unable to reproduce Wakefield's findings or confirm his hypothesis of an association between the MMR vaccine and autism, or autism and gastrointestinal disease.
As of January 2011, Wakefield continued to maintain his innocence. In a press release, he stated,  I want to make one thing crystal clear for the record--my research and the serious medical problems found in those children were not a hoax and there was no fraud whatsoever. Nor did I seek to profit from our findings ... despite media reports to the contrary, the results of my research have been duplicated in five other countries ... I continue to fully support more independent research to determine if environmental triggers, including vaccines, are causing autism and other developmental problems ... Since the Lancet [sic] paper, I have lost my job, my career and my country. To claim that my motivation was profit is patently untrue. I will not be deterred--this issue is far too important.  In an internet radio interview, Wakefield said the BMJ series "was utter nonsense" and denied "that he used the cases of the 12 children in his study to promote his business venture". Although Deer is funded by The Sunday Times and Channel 4, he has filed financial disclosure forms and denies receiving any funding from the pharmaceutical industry, which Wakefield says is paying him. According to CNN, Wakefield said the patent he held was for "an 'over-the-counter nutritional supplement' that boosts the immune system". WebMD reported that Wakefield said he was the victim of "a ruthless, pragmatic attempt to crush any attempt to investigate valid vaccine safety concerns".  Wakefield says that Deer is a "hit man who was brought in to take [him] down" and that other scientists have simply taken Deer at his word. While on Anderson Cooper 360deg, he said that he had not read the BMJ articles yet, but he denied their validity and denied that Deer had interviewed the families of the children in the study. He also urged viewers to read his book, Callous Disregard, which he said would explain why he was being targeted, to which Anderson Cooper replied: "But sir, if you're lying, then your book is also a lie. If your study is a lie, your book is a lie."  Wakefield later implied that there is a conspiracy by public health officials and pharmaceutical companies to discredit him, including suggesting they pay bloggers to post rumours about him on websites or that they artificially inflated reports of deaths from measles.

was there any controversy about his studies?

medical problems found in those children were not a hoax

IN: James Anthony Traficant Jr. (May 8, 1941 - September 27, 2014) was a Democratic, and later independent, politician and member of the United States House of Representatives from Ohio. He represented the 17th Congressional District, which centered on his hometown of Youngstown and included parts of three counties in northeast Ohio's Mahoning Valley. He was expelled from the House after being convicted of taking bribes, filing false tax returns, racketeering and forcing his aides to perform chores at his farm in Ohio and houseboat in Washington, D.C.

In the House, Traficant was known for his flamboyant and eccentric style. He often dressed poorly, with narrow neckties (then out of style), wide-lapel sport-coats and an occasional denim suit. He also sported an unkempt pompadour, which he jokingly claimed he cut with a weed whacker (it was revealed, after his conviction, that he wore a toupee). His trademark closing lines while addressing the House were "Beam me up..." and "I yield back the fact..." His website featured a picture of him swinging a two-by-four with the words "Bangin' away in D.C."  While in Congress, Traficant was a supporter of immigration reduction, and a strong opponent of illegal immigration. In the controversy surrounding the defeat of Congressman Bob Dornan (R-CA) by Democrat Loretta Sanchez, Traficant was the only Democratic member of Congress who advocated a new election, due to Dornan's allegations of voting in that race by undocumented immigrants (the allegations went unproven, and a new election was not held).  Traficant's major legislative accomplishment in the House was the adoption of some of his proposals to constrain enforcement activities by the Internal Revenue Service against delinquent taxpayers.  After the Republicans took control of the House in 1995, Traficant tended to vote more often with the Republicans than with his own party. On the issue of abortion, Traficant voted with the position of the National Right to Life Committee 95% of the time in the 105th Congress, and 100% of the time in the 106th and 107th Congresses. However, he voted against all four articles of impeachment against Bill Clinton. After he voted for Republican Dennis Hastert for Speaker of the House in 2001, the Democrats stripped him of his seniority and refused to give him any committee assignments. Because the Republicans did not assign him to any committees either, Traficant became the first member of the House of Representatives in over a century--outside the top leadership--to lack a single committee assignment.

anything interesting about him to know?
