Document 4: John Kerry: Meanwhile, Kerry's staff began their own investigations and, on October 14, issued a report that exposed illegal activities on the part of Lieutenant Colonel Oliver North, who had set up a private network involving the National Security Council and the CIA to deliver military equipment to right-wing Nicaraguan rebels (Contras). In effect, North and certain members of the President's administration were accused by Kerry's report of illegally funding and supplying armed militants without the authorization of Congress. Kerry's staff investigation, based on a year-long inquiry and interviews with fifty unnamed sources, is said to raise "serious questions about whether the United States has abided by the law in its handling of the contras over the past three years."

Document 6: Shady Grove, Iowa: Shady Grove is a former townsite and unincorporated community in Buchanan County, Iowa, United States, between the cities of Brandon and Jesup. Settlement of Shady Grove began in 1857, but with the advent of rural migration, the population had dropped to 25 by the 1950s. New housing developments begun during the 1990s and 2000s, however, have caused the empty community to be reborn, causing controversy along the way.
Document 7: John Kerry: The Kerry Committee report found that "the Contra drug links included..... payments to drug traffickers by the U.S. State Department of funds authorized by the Congress for humanitarian assistance to the Contras, in some cases after the traffickers had been indicted by federal law enforcement agencies on drug charges, in others while traffickers were under active investigation by these same agencies." The U.S. State Department paid over $806,000 to known drug traffickers to carry humanitarian assistance to the Contras. Kerry's findings provoked little reaction in the media and official Washington.
Document 8: John Kerry: On April 18, 1985, a few months after taking his Senate seat, Kerry and Senator Tom Harkin of Iowa traveled to Nicaragua and met the country's president, Daniel Ortega. Though Ortega had won internationally certified elections, the trip was criticized because Ortega and his leftist Sandinista government had strong ties to Cuba and the USSR and were accused of human rights abuses. The Sandinista government was opposed by the right-wing CIA-backed rebels known as the Contras. While in Nicaragua, Kerry and Harkin talked to people on both sides of the conflict. Through the senators, Ortega offered a cease-fire agreement in exchange for the U.S. dropping support of the Contras. The offer was denounced by the Reagan administration as a "propaganda initiative" designed to influence a House vote on a $14 million Contra aid package, but Kerry said "I am willing..... to take the risk in the effort to put to test the good faith of the Sandinistas." The House voted down the Contra aid, but Ortega flew to Moscow to accept a $200 million loan the next day, which in part prompted the House to pass a larger $27 million aid package six weeks later.

Document 12: John Kerry: During his bid to be elected president in 2004, Kerry frequently criticized President George W. Bush for the Iraq War. While Kerry had initially voted in support of authorizing President Bush to use force in dealing with Saddam Hussein, he voted against an $87 billion supplemental appropriations bill to pay for the subsequent war. His statement on March 16, 2004, "I actually did vote for the $87 billion before I voted against it," helped the Bush campaign to paint him as a flip-flopper and has been cited as contributing to Kerry's defeat.
Document 13: John Kerry: During their investigation of Noriega, Kerry's staff found reason to believe that the Pakistan-based Bank of Credit and Commerce International (BCCI) had facilitated Noriega's drug trafficking and money laundering.

In December 1992, Kerry and Senator Hank Brown, a Republican from Colorado, released The BCCI Affair, a report on the BCCI scandal. The report showed that the bank was crooked and was working with terrorists, including Abu Nidal.
