[8][10] The second of six children, Bob Jr. lived as a boy in Malaysia, Pakistan, Panama, Peru, Baghdad,[11] and finally Tehran, Iran, where he graduated from Community High School in 1966.

[2] His office prosecuted state and local officials, members of the Medellin drug cartel, and got a perjury indictment on then-sitting Republican Congressman Pat Swindall,[20] who ultimately served a year in prison on the charges.

From 1990 to 1991, Barr was president of the Southeastern Legal Foundation.,[21] an Atlanta-based law firm and policy center that litigates in support of "limited government, individual economic freedom, and the free enterprise system".

"[29] Barr said in 2010, "I can see a situation where the federal government is going to bring an entire suitcase of San Francisco values to the American family, and while I would love to explain all the things that are wrong with that, the fact is that this is a corrupting, left-leaning, influence on a section of society that so many liberal elites want to see taken out of the 'red state' column.

And any member of Congress – Democrat or Republican – who introduces legislation to make federal drug laws even more oppressive could be next on our list.However, some individuals within these groups lamented Barr's defeat as a setback for privacy rights[36] and libertarian causes in general.

[40] Barr was originally a strong supporter of the War on Drugs, reflecting his previous experience as an Anti-Drug Coordinator for the United States Department of Justice.

[38] This task force was established in 1998 by then-Speaker Newt Gingrich to "design a World War II-style victory plan to save America's children from illegal drugs.

[43][44] Nearly a year passed before a lawsuit[45] filed by the American Civil Liberties Union eventually revealed the initiative had received 69 percent of the vote.

[53][54] In 2009, both the United States Senate and House of Representatives voted to lift the ban against a medical marijuana initiative, effectively overturning the Barr Amendment.

[64] Barr played a similar role during the debate over Bill Clinton's Comprehensive Anti-terrorism Act of 1995, crafting pro-civil liberties amendments to the original text.

A press release from Barr's presidential campaign stated: "The next president should commit to a speedy and complete withdrawal from Iraq, and tell the Iraqi people that the U.S. troops will be going home.

[70] The National Review described Barr as one of the few people able to "ask effective questions and make clear points" while questioning government witnesses during the 1995 House Waco siege hearings on the Bureau of Alcohol, Tobacco, Firearms and Explosives and Federal Bureau of Investigation actions against the Branch Davidians in 1993, sponsored by subcommittees of the House Judiciary Committee and Government Reform and Oversight Committee.

[71] Barr has written: "The hearing was a farce: a virtual lovefest, during which members of the Clinton Administration responded to softball questions from their colleagues in the House with superficial answers, and Republican queries were ignored or glossed over with disdain, if not outright contempt.

In the spring of 1997, Republican, Bob Barr, wrote House Committee on the Judiciary chairman Henry Hyde, encouraging him to open an impeachment inquiry.

[79] Foremost among the concerns Barr cited at the time was apparent obstruction of Justice Department investigations into Clinton campaign fundraising from foreign sources, chiefly the People's Republic of China.

These members were Roscoe Bartlett, Helen Chenoweth, Barbara Cubin, John Doolittle, Lindsey Graham, Duncan L. Hunter, Sam Johnson, Jack Kingston, Jack Metcalf, John Mica, Ron Paul, Dana Rohrabacher, Pete Sessions, Chris Smith, Mark Souder, Linda Smith, Bob Stump, and Todd Tiahrt.

[81] After the Clinton–Lewinsky scandal came to light, Barr ramped up his efforts to push for Clinton's impeachment, appearing regularly on television, as well as even publishing a scholarly article in the Texas Law Review on the subject.

[82] During debate on the 1998 impeachment resolution on the House floor, Barr argued that Clinton's attempt to interfere with Lewinsky's testimony in the Paula Jones case endangered the Constitution.

"[83] In 1999, during Clinton's impeachment trial, Hustler publisher Larry Flynt offered money to anyone who could provide evidence about prominent Republicans who had engaged in an extramarital affair.

[11][85] Investigators reported that Bob Barr then "invoked a legal privilege from his 1985 divorce proceeding so he could refuse to answer questions on whether he'd cheated on his second wife with the woman who is now his third" (Jerilyn).

[86] A man faithful to the Constitution doesn't stop criticizing presidents when the letter after their names change.Since leaving Congress in 2003, Barr has become a vocal opponent of the Patriot Act and has stated that he voted for it reluctantly[11] and regrets voting for it, only agreeing because the Bush administration promised not to attempt to expand the granted powers or use them for non-terrorism purposes, and the administration agreed to report to Congress on their usage.

[87] Barr says that the Bush administration promptly ignored these three promises given to Congress and has used the powers granted from the Patriot Act to further erode due process of law even in matters unrelated to terrorism.

Barr has been a vocal opponent of President George W. Bush's claim of authorization to wiretap transnational phone calls without individual judicial license.

[96] In January 2006, to emphasize the bipartisan nature of the event, Barr planned on introducing Al Gore at a speech co-sponsored by the Liberty Coalition and the American Constitution Society for Law and Policy to address what they called the "NSA Spying Scandal", in which Gore compared warrantless wiretapping to the FBI's illegal COINTELPRO project surveilling, discrediting and disrupting Martin Luther King Jr.[97] On December 12, 2006, Barr became a regional representative on the Libertarian National Committee, representing the Party's Southeast Region.

Barr said: "I'm happy to announce that I am now a proud, card-carrying Libertarian who is committed to helping elect leaders who will strive for smaller government, lower taxes and abundant individual freedom.

[115] In August 2008, Barr published an opinion piece in The Washington Times that criticized the United States' response to the conflict between Russia and Georgia as being too emotional and not based on legitimate American national security concerns.

In 2008, in an Op-Ed article published in The Atlanta Journal-Constitution, Barr lambasted the new policy of Boston, Massachusetts police to allow warrantless search for firearms in teenagers' homes.

[134] In July, he filed a lawsuit against Oklahoma for its unusually restrictive ballot access laws,[135] which he contends are contrary to the First Amendment right to petition one's government for a redress of grievances.

[144] Despite strong polling numbers, Barr chose to abandon his plans for running, citing concern on the potential impact it would have on his law firm and family.

[143] Barr held a news conference on March 28, 2013, at Adventure Outdoors in Smyrna, Georgia where he announced his upcoming run for his old congressional seat, the 11th.
