Some context: Biden was born on November 20, 1942, at St. Mary's Hospital in Scranton, Pennsylvania, to Catherine Eugenia "Jean" Biden (nee Finnegan) and Joseph Robinette "Joe" Biden Sr. He was the first of four siblings in a Catholic family, with a sister, Valerie, and two brothers, James and Frank, following. His mother was of Irish descent, with roots variously attributed to County Louth or County Londonderry. His paternal grandparents, Mary Elizabeth (Robinette) and Joseph H. Biden, an oil businessman from Baltimore, Maryland, were of English, French, and Irish ancestry.
On August 27, 1966, while Biden was still a law student, he married Neilia Hunter. They overcame her parents' initial reluctance for her to wed a Roman Catholic, and the ceremony was held in a Catholic church in Skaneateles. They had three children, Joseph R. "Beau" Biden III in 1969, Robert Hunter in 1970, and Naomi Christina in 1971.  During 1968, Biden clerked for six months at a Wilmington law firm headed by prominent local Republican William Prickett and, as he later said, "thought of myself as a Republican". He disliked the conservative racial politics of incumbent Democratic Governor of Delaware Charles L. Terry and supported a more liberal Republican, Russell W. Peterson, who defeated Terry in 1968. The local Republicans tried to recruit him, but he resisted due to his distaste for Republican presidential candidate Richard Nixon, and registered as an Independent instead.  In 1969, Biden resumed practicing law in Wilmington, first as a public defender and then at a firm headed by Sid Balick, a locally active Democrat. Balick named him to the Democratic Forum, a group trying to reform and revitalize the state party, and Biden switched his registration to Democrat. He also started his own firm, Biden and Walsh. Corporate law, however, did not appeal to him and criminal law did not pay well. He supplemented his income by managing properties.  Later in 1969, Biden ran as a Democrat for the New Castle County Council on a liberal platform that included support for public housing in the suburban area. He won by a solid, two-thousand vote margin in the usually Republican district and in a bad year for Democrats in the state. Even before taking his seat, he was already talking about running for the U.S. Senate in a couple of years. He served on the County Council from 1970 to 1972 while continuing his private law practice. Among issues he addressed on the council was his opposition to large highway projects that might disrupt Wilmington neighborhoods, including those related to Interstate 95.

Some context: Khalid El-Masri (also Khaled El-Masri and Khaled Masri, Levantine Arabic pronunciation: ['xa:lId el'mas?ri, -'mas?re], Arabic: khld lmSry) (born June 29, 1963) is a German and Lebanese citizen who was mistakenly abducted by the Macedonian police in 2003, and handed over to the U.S. Central Intelligence Agency (CIA). While in CIA custody, he was flown to Afghanistan, where he was held at a black site and routinely interrogated, beaten, strip-searched, sodomized, and subjected to other cruel forms of inhumane and degrading treatment and torture.
After his release, in 2006 El-Masri wrote in the Los Angeles Times that, while held by the CIA in Afghanistan, he was beaten and repeatedly interrogated. He also said that his custodians forcibly inserted an object into his anus. He was kept in a bare, squalid cell, given only meager rations to eat and putrid water to drink.  According to a report by the inspector general of the CIA, El-Masri's German passport was not examined for authenticity until three months into his detention. Upon examination, the CIA's Office of Technical Services swiftly concluded it was genuine and that his continued detention would be unjustified. Discussion over what to do with El-Masri included secretly transporting him back to Macedonia and dumping him there without informing German authorities, and denying any claims he made.  In March 2004, El-Masri took part in a hunger strike, demanding that his captors afford him due process or watch him die. After 27 days without eating, he forced a meeting with the prison director and a CIA officer known as "The Boss". They conceded he should not be imprisoned but refused to release him. El-Masri continued his hunger strike for 10 more days until he was force-fed and given medical attention. He had lost more than 60 pounds (27 kg) since his abduction in Skopje.  While imprisoned in Afghanistan, Masri befriended several other detainees. The men memorized each other's telephone numbers so that if one was released, he could contact the families of the others. According to the New York Times, Laid Saidi, an Algerian who was a former detainee, was released in 2006. His description of his abduction and detention closely matched that of El-Masri.  El-Masri reports that Majid Khan, characterized by the Bush administration as a high-value detainee, was held in the Salt Pit at the same time as he was. Khan, a former resident of Catonsville, Maryland, was held by the CIA for an additional three and a half years prior to being transferred to US military custody and Guantanamo on September 5, 2006.
