 Passage 2:In the late-1990s, Cantrell established as a professional backing vocalist for artists such as Sean "Puffy" Combs. In 1999, she became member of the girl band 8th Avenue, a protegé of singer Teddy Riley. While the band recorded several songs and appeared on Blackstreet's 1999 album Finally, their material was left unused after Riley left Blackstreet to reform his previous group Guy and Blackstreet were subsequently dropped by Interscope Records, also leading to 8th Avenue's disbandment. Soon after, Cantrell was introduced by both a dancer friend and R&B singer Usher to Red Zone Entertainment head, music producer Tricky Stewart. Stewart originally wanted her to become a member of his girl group 321, but soon offered Cantrell to work with her as a solo artist following a fruitful recording session. Cantrell subsequently moved in with Stewart and his girlfriend in their Atlanta house, and was promptly placed with Arista Records head Antonio "L.A." Reid who offered the singer a contract with the company after hearing one song she wrote and sang in front of him and his staff. After a bidding war with several different labels, Reid's bid was the highest, prompting Cantrell to sign with them.
 Passage 3:In the years since September 11, 2001, Clinton has been subject to criticism that he failed to capture Osama bin Laden as President. In a September 24, 2006, interview with Fox News' Chris Wallace on Fox News Sunday, Clinton challenged his critics. According to Clinton, he faced criticism from various conservatives during his administration for being too obsessed with Bin Laden. Clinton also noted that his administration created the first comprehensive anti-terrorist operation, led by Richard Clarke—whom Clinton accuses the Bush Administration of demoting. Clinton also said he worked hard to try to kill Bin Laden. Former international negotiator and current businessman, financier and media commentator Mansoor Ijaz claimed that from 1996–1998, he had opened up unofficial negotiations with Sudan to lift terrorism sanctions from that country in exchange for intelligence information about the terrorist groups Islamic Jihad, Hezbollah and Hamas. He claimed that Sudan was also prepared to offer custody of terrorist mastermind Osama bin Laden, who had been living in the country and launching operations. According to Ijaz, neither Clinton nor National Security Advisor Sandy Berger responded to the situation. Bin Laden later left Sudan and established his operations in Afghanistan under the protection of the Taliban and, with his network, planned out terrorist attacks against American interests worldwide, including attacks on American embassies in Tunisia and Sudan as well as the bombing of USS Cole. The most infamous were the attacks of September 11, 2001 that occurred under Clinton's successor, George W. Bush nine months after Clinton left office. However, the 9/11 Commission Report later found no credible evidence to support the Sudan custody offer as the American Ambassador to the Sudan had no legal basis to ask for custody due to no indictment against Bin Laden:
