Problem: Frederick Douglass (born Frederick Augustus Washington Bailey; c. February 1818 - February 20, 1895) was an African-American social reformer, abolitionist, orator, writer, and statesman. After escaping from slavery in Maryland, he became a national leader of the abolitionist movement in Massachusetts and New York, gaining note for his oratory and incisive antislavery writings. In his time, he was described by abolitionists as a living counter-example to slaveholders' arguments that slaves lacked the intellectual capacity to function as independent American citizens. Northerners at the time found it hard to believe that such a great orator had once been a slave.

The couple settled in New Bedford, Massachusetts. After meeting and staying with Nathan and Mary Johnson, they adopted Douglass as their married name: previously Douglass had been given the second name of Bailey, but he now again felt the need to find a new name and asked Johnson to choose a suitable surname. Johnson had been reading The Lady of the Lake, and suggested "Douglass" after the principal character in the poem. Douglass thought of joining a white Methodist Church but from the beginning he was disappointed when he saw it was segregated. Later he joined the African Methodist Episcopal Zion Church, an independent black denomination first established in New York City, which counted among its members Sojourner Truth and Harriet Tubman. He became a licensed preacher in 1839, and this helped him hone his oratorical skills. He held various positions, including steward, Sunday School superintendent, and sexton. In 1840, Douglass delivered a speech in Elmira, New York, then a station on the Underground Railroad. (Years later a black congregation formed there and by 1940 it became the region's largest church). Douglass also joined several organizations in New Bedford, and regularly attended abolitionist meetings. He subscribed to William Lloyd Garrison's weekly journal The Liberator. Inspired by Garrison, Douglass later said, "no face and form ever impressed me with such sentiments [of the hatred of slavery] as did those of William Lloyd Garrison." So deep was this influence that in his last biography, Douglass confessed "his paper took a place in my heart second only to The Bible." Garrison was likewise impressed with Douglass, and had written about his anti-colonialism stance in The Liberator as early as 1839. In 1841, Douglass first heard Garrison speak at a meeting of the Bristol Anti-Slavery Society. At another meeting, Douglass was unexpectedly invited to speak. After telling his story, Douglass was encouraged to become an anti-slavery lecturer. A few days later Douglass spoke at the Massachusetts Anti-Slavery Society's annual convention in Nantucket. Then 23 years old, Douglass conquered his nervousness and gave an eloquent speech about his rough life as a slave. In 1843, Douglass joined other speakers in the American Anti-Slavery Society's "Hundred Conventions" project, a six-month tour at meeting halls throughout the Eastern and Midwestern United States. During this tour, slavery supporters frequently accosted Douglass. At a lecture in Pendleton, Indiana, an angry mob chased and beat Douglass before a local Quaker family, the Hardys, rescued him. His hand was broken in the attack; it healed improperly and bothered him for the rest of his life. A stone marker in Falls Park in the Pendleton Historic District commemorates this event.

when did he become an abolitionist?

Answer with quotes: In 1843,

Background: Richard John Santorum (born May 10, 1958) is an American attorney, author, politician, and CNN Senior Political Commentator. A member of the Republican Party, he served as a United States Senator from Pennsylvania from 1995 to 2007 and was the Senate's third-ranking Republican from 2001 to 2007. He ran as a candidate for the 2012 Republican Party presidential nomination, finishing second to Mitt Romney. Santorum was elected as a United States Senator from Pennsylvania in 1994.
Context: Santorum served in the United States Senate representing Pennsylvania from 1995 to 2007. From 2001 until 2007, he was the Senate's third-ranking Republican. He was first elected to the Senate during the 1994 Republican takeover, narrowly defeating incumbent Democrat Harris Wofford, 49% to 47%. The theme of Santorum's 1994 campaign signs was "Join the Fight!" During the race, he was considered an underdog, as his opponent was 32 years his senior. He was reelected in 2000, defeating U.S. Congressman Ron Klink by a 52-46% margin. In his reelection bid of 2006, he lost to Democrat Bob Casey, Jr. by a 59-41% margin. After his election to the Senate in 1994, Santorum sought to "practice what [he] preached" and hired five people for his staff who were on welfare, food stamps, or other government aid. In 1996, Santorum served as Chairman of the Republican Party Task Force on Welfare Reform, and contributed to legislation that became the Personal Responsibility and Work Opportunity Act. Santorum was an author and the floor manager of the bill. In 1996, Santorum endorsed moderate Republican Arlen Specter in his short-lived campaign for president. Reporters have observed that though Santorum and Specter differed on social policy, Specter provided him with key political staff for his successful run in 1994. The National Taxpayers Union, a fiscal conservative organization, gave Santorum an "A-" score for his votes on fiscal issues, meaning that he was one of "the strongest supporters of responsible tax and spending policies" during his tenure, and ranked fifth in the group's rankings out of 50 senators who served at the same time.
Question: What years did he serve as chairman?
Answer: 1996,

Question:
Jason Gilbert Giambi (; born January 8, 1971) is an American former professional baseball first baseman and designated hitter. In his Major League Baseball (MLB) career, which began in 1995, he played for the Oakland Athletics, New York Yankees, Colorado Rockies and Cleveland Indians. Giambi was the American League MVP in 2000 while with the Athletics, and is a five-time All-Star who led the American League in walks four times, in on-base percentage three times, and in doubles and in slugging percentage once each, and won the Silver Slugger Award twice. Giambi has publicly apologized for using performance-enhancing drugs during his career.
Late in 2003, Giambi was named by FBI officers investigating the Bay Area Laboratory Co-operative (BALCO) as being one of the baseball players believed to have received anabolic steroids from trainer Greg Anderson. In December 2004, the San Francisco Chronicle reported it had seen Giambi's 2003 grand jury testimony in the BALCO investigation. The newspaper said that in his testimony, Giambi admitted to using several different steroids during the off-seasons from 2001 to 2003, and injecting himself with human growth hormone during the 2003 season. In a press conference prior to the 2005 season, Giambi apologized publicly to the media and his fans, though he did not specifically state what for. The lawyer who illegally leaked the testimony later pleaded guilty, and was sentenced to 2 and a half years in prison. Giambi apologized again on May 16, 2007, this time specifically for using steroids, and urged others in the sport to do the same. "I was wrong for using that stuff", he told USA Today. "What we should have done a long time ago was stand up--players, ownership, everybody--and said, 'We made a mistake.'" When asked why he used steroids, Giambi responded: "Maybe one day I'll talk about it, but not now." Giambi did speak with George J. Mitchell, after being forced to do so by Bud Selig. Subsequently, in December 2007, the Mitchell Report included Giambi along with his brother Jeremy Giambi, who also admitted to using steroids during his career. The prosecution in the Barry Bonds perjury case indicated they intended to call both Jason and Jeremy Giambi to testify against Bonds in his March 2009 trial.
