Operation Fast and Furious involved the Obama administration arming drug cartels and thugs south of the border as a means to undermine the Second Amendment. The program resulted in the death of U.S. Border Patrol agent Brian Terry. One of the Islamic terrorists in the Garland, Texas, attack also used a gun that was obtained through the Fast and Furious program. http://www.judicialwatch.org/press-room/press-releases/judicial-watch-justice-department-documents-reveal-widespread-use-fast-furious-weapons-major-mexican-drug-cartels-linked-least-69-killings/

The terror attacks in Benghazi, Libya resulted in four brave Americans dying despite the fact that help could have been sent, but wasn't. Requests for security prior to the attack were repeatedly denied, and after the attack Obama and Hillary Clinton falsely blamed it on a video considered offensive to Muslims. http://dailycaller.com/2016/06/28/benghazi-report-claims-government-officials-failed-to-act-on-obamas-orders/

In 2013, Lois Lerner, who directed the Internal Revenue Service's Exempt Organizations Unit, admitted that Tea Party organizations were targeted under the agency, but blamed it on lower-level employees. Such organizations were heavily scrutinized with invasive questions. Since then, Lerner and IRS commissioner John Koskinen have denied any wrongdoing and have stonewalled congressional efforts to investigate the matter, citing computer crashes for being unable to turn over related emails. https://www.washingtonpost.com/business/economy/irs-admits-targeting-conservatives-for-tax-scrutiny-in-2012-election/2013/05/10/3b6a0ada-b987-11e2-92f3-f291801936b8_story.html?utm_term=.7b3f7da37fa2

The DOJ seized Associated Press phone records as well as phone and email records from Fox News reporter James Rosen https://www.washingtonpost.com/world/national-security/under-sweeping-subpoenas-justice-department-obtained-ap-phone-records-in-leak-investigation/2013/05/13/11d1bb82-bc11-11e2-89c9-3be8095fe767_story.html?utm_term=.155ca08880bf

Thanks to leaking from former government contractor Edward Snowden, it was revealed that the National Security Agency had been conducting mass surveillance against American citizens—a clear violation of the Fourth Amendment. In 2015, the NSA eventually ended their bulk data collection of phone records. https://en.wikipedia.org/wiki/PRISM_(surveillance_program)

The Obama administration claimed that they were giving a total of $1.7 billion to Iran to settle a failed arms deal with the previous Iranian regime, and it just happened to coincide with the release of four American hostages. The Obama administration also didn't reveal the details of the agreement to Congress. It was obvious though that it was a ransom deal and the Obama administration lied about it. http://www.wsj.com/articles/u-s-sent-cash-to-iran-as-americans-were-freed-1470181874

Clinton's use of a private email server that was unapproved and unsecured has been written about extensively, but it is also Obama's scandal as well, since it has been revealed that not only did Obama know about her private email server, he also communicated with her under the use of a pseudonym. http://thehill.com/blogs/blog-briefing-room/news/297570-obama-used-pseudonym-in-emails-with-clinton

The EPA breached the Gold King mine in the state and "mistakenly dug at the bottom" as well as didn't test for pressure, leading to "three million gallons of toxic mine waste" being dumped into a river https://www.washingtonpost.com/news/energy-environment/wp/2015/08/12/epa-chief-seeks-damage-control-after-spill-of-toxic-waste-into-colorado-river/?utm_term=.947f3cc995db

The nonpartisan Government Accountability Office concluded that the EPA broke the law in using Thunderclap to tout their "Waters of the United States" regulation as well as their use of "hyperlinks to the [Natural Resources Defense Council] and Surfrider Foundation webpages provided in the EPA blog post." https://www.nytimes.com/2015/12/15/us/politics/epa-broke-the-law-by-using-social-media-to-push-water-rule-auditor-finds.html?_r=0

The General Services Administration was busted in 2012 for spending $823,000 on an extravagantly decadent conference in Las Vegas, and it became a shining example of government waste. Several people in the agency were fired, with one facing an indictment. Despite the scandal, lavish spending still occurred within federal agencies under the Obama administration.

The Secret Service was caught in 2012 engaging with prostitutes during a trip to Cartegena, Columbia, with one Secret Service agent emailing another: "Swagg cologne-check/Pimp gear-check/ Swagg sunglasses-check/Cash fo dem hoes-check."
