IN: Jonas Edward Salk (; October 28, 1914 - June 23, 1995) was an American medical researcher and virologist. He discovered and developed one of the first successful polio vaccines. Born in New York City, he attended New York University School of Medicine, later choosing to do medical research instead of becoming a practicing physician. In 1939, after earning his medical degree, Salk began an internship as a physician scientist at Mount Sinai Hospital.

In 1947, Salk became ambitious for his own lab and was granted one at the University of Pittsburgh, but the lab was smaller than he had hoped and he found the rules imposed by the university restrictive. In 1948, Harry Weaver, the director of research at the National Foundation for Infantile Paralysis, contacted Salk. He asked Salk to find out if there were more types of polio than the three then known, offering additional space, equipment and researchers. For the first year he gathered supplies and researchers including Julius Youngner, Byron Bennett, L. James Lewis, and secretary Lorraine Friedman joined Salk's team, as well. As time went on, Salk began securing grants from the Mellon family and was able to build a working virology laboratory. He later joined the National Foundation for Infantile Paralysis's polio project established by President Franklin D. Roosevelt. Extensive publicity and fear of polio led to much increased funding, $67 million by 1955, but research continued on dangerous live vaccines. Salk decided to use the safer 'killed' virus, instead of weakened forms of strains of polio viruses like the ones used contemporarily by Albert Sabin, who was developing an oral vaccine. After successful tests on laboratory animals, on July 2, 1952, assisted by the staff at the D.T. Watson Home for Crippled Children, Salk injected 43 children with his killed-virus vaccine. A few weeks later, Salk injected children at the Polk State School for the retarded and feeble-minded. In 1954 he tested the vaccine on about one million children, known as the polio pioneers. The vaccine was announced as safe on April 12, 1955. The project became large, involving 100 million contributors to the March of Dimes, and 7 million volunteers. The foundation allowed itself to go into debt to finance the final research required to develop the Salk vaccine. Salk worked incessantly for two and a half years. Salk's inactivated polio vaccine was the first vaccine for the disease; it came into use in 1955. It is on the World Health Organization's List of Essential Medicines, the most effective and safe medicines needed in a health system.
QUESTION: When did Salk do polio research?
IN: John Owen Brennan (born September 22, 1955) was the Director of the Central Intelligence Agency (CIA) from March 2013 to January 2017. He served as chief counterterrorism advisor to U.S. President Barack Obama; his title was Deputy National Security Advisor for Homeland Security and Counterterrorism, and Assistant to the President. His responsibilities included overseeing plans to protect the country from terrorism and respond to natural disasters, and he met with the President daily. Previously, he advised President Obama on foreign policy and intelligence issues during the 2008 presidential campaign and transition.

United States President Barack Obama twice nominated Brennan to serve as Director of the Central Intelligence Agency. Morris Davis, a former Chief Prosecutor for the Guantanamo Military Commissions compared Brennan to Canadian Omar Khadr, who was convicted of "committing murder in violation of the law of war". He suggested that Brennan's role in targeting individuals for CIA missile strikes was no more authorized than the throwing of the grenade of which Khadr was accused. On February 27, 2013, the Senate Intelligence Committee postponed a vote, expected to be taken the next day on the confirmation of Brennan until the following week. On March 5, the Intelligence Committee approved the nomination 12-3. The Senate was set to vote on Brennan's nomination on March 6, 2013. However, Kentucky Senator Rand Paul began a talking Senate filibuster of the vote, citing President Barack Obama and his administration's use of combat drones against Americans, stating "No one politician should be allowed to judge the guilt, to charge an individual, to judge the guilt of an individual and to execute an individual. It goes against everything that we fundamentally believe in our country." Paul's filibuster continued for 13 hours, ending with the words: "I'm hopeful that we have drawn attention to this issue, that this issue will not fade away, and that the president will come up with a response." After the filibuster, Brennan was confirmed by a vote of 63-34. Brennan was sworn into the office of CIA Director on March 8, 2013. in a 63-44 vote.
QUESTION: How long did he hold this position?
IN: Ahmed Yassin was born in al-Jura, a small village near the city of Ashkelon, in the British Mandate of Palestine. His date of birth is not known for certain: according to his Palestinian passport, he was born on 1 January 1929, but he claimed to have actually been born in 1937. His father, Abdullah Yassin, died when he was three years old. Afterward, he became known in his neighborhood as Ahmad Sa'ada after his mother Sa'ada al-Habeel.

Yassin was a founder and prominent leader of Hamas, which is regarded as a terrorist organization by a number of national governments. Israeli Prime Minister Ariel Sharon characterized Yassin as the "mastermind of Palestinian terror" and a "mass murderer." The Israeli government repeatedly asserted that Yassin was responsible for a number of terrorist attacks, which targeted and killed a number of civilians. They accused him of being behind all the attacks perpetrated by Hamas against Israel. Israel said the targeted killing was in response to dozens of suicide attacks by Hamas against Israeli civilians. According to an Israeli government website: Yassin was the dominant authority of the Hamas leadership, which was directly involved in planning, orchestrating and launching terror attacks carried out by the organization. In this capacity, Yassin personally gave his approval for the launching of Qassam rockets against Israeli cities, as well as for the numerous Hamas terrorist bombings and suicide operations. In his public appearances and interviews, Yassin called repeatedly for a continuation of the 'armed struggle' against Israel, and for an intensification of the terrorist campaign against its citizens. The successful operation against Yassin constitutes a significant blow to a central pillar of the Hamas terrorist organization, and a major setback to its terrorist infrastructure. In his statement Yassin declared that Hamas did target Israeli civilians, but only in direct retaliation for the death of Palestinian civilians. In his thinking this was a necessary tactic to "show the Israelis they could not get away without a price for killing our people."
