1. In the United States, a 401(k) plan is the tax-qualified, defined-contribution pension account defined in subsection 401(k) of the Internal Revenue Code. Under the plan, retirement savings contributions are provided (and sometimes proportionately matched) by an employer, deducted from the employee's paycheck before taxation (therefore tax-deferred until withdrawn after retirement or as otherwise permitted by applicable law), and limited to a maximum pre-tax annual contribution of $18,000 (as of 2015). 2. Cindy Lee Miller Sheehan (born July 10, 1957) is an American anti-war activist, whose son, U.S. Army Specialist Casey Sheehan, was killed by enemy action during the Iraq War. She attracted national and international media attention in August 2005 for her extended antiwar protest at a makeshift camp outside President George W. Bush's Texas ranch—a stand that drew both passionate support and criticism. Sheehan ran unsuccessfully for Congress in 2008. She is a vocal critic of President Barack Obama's foreign policy. Her memoir, Peace Mom: A Mother's Journey Through Heartache to Activism, was published in 2006. Sheehan was the 2012 vice-presidential nominee of the Peace and Freedom Party, and received 1.2% of the statewide vote in the 2014 California gubernatorial election. 3. The Plame affair (also known as the CIA leak scandal and Plamegate) was a political scandal that revolved around journalist Robert Novak's public identification of Valerie Plame as a covert Central Intelligence Agency officer in 2003.In 2002, Plame wrote a memo to her superiors in which she expressed hesitation in recommending her husband, former diplomat Joseph C. Wilson, to the CIA for a mission to Niger to investigate claims that Iraq had arranged to purchase and import uraniumfrom the country, but stated that he "may be in a position to assist". After President George W. Bushstated that "Saddam Hussein recently sought significant quantities of uranium from Africa" during the run-up to the 2003 invasion of Iraq, Wilson published a July 2003 op-ed in The New York Timesstating his doubts during the mission that any such transaction had taken place.[Note 1]A week after Wilson's op-ed was published, Novak published a column which mentioned claims from "two senior administration officials" that Plame had been the one to suggest sending her husband. Novak had learned of Plame's employment, which was classified information, from State Departmentofficial Richard Armitage. David Corn and others suggested that Armitage and other officials had leaked the information as political retribution for Wilson's article.The scandal led to a criminal investigation; no one was charged for the leak itself. Scooter Libby was convicted of lying to investigators. His prison sentence was ultimately commuted by President Bush. 4. The NSA warrantless surveillance controversy("warrantless wiretapping") concerns surveillance of persons within the United States during the collection of allegedly foreign intelligence by the U.S. National Security Agency (NSA) as part of the touted war on terror. Under this program, referred to by the Bush administration as the terrorist surveillance program, part of the broader President's Surveillance Program, the NSA was authorized by executive order to monitor, without search warrants, the phone calls, Internet activity (Web, e-mail, etc.), text messaging, and other communication involving any party believed by the NSA to be outside the U.S., even if the other end of the communication lies within the U.S. However, it has been discovered that all U.S. communications have been digitally cloned by government agencies, in apparent violation of unreasonable search and seizure.Critics claim that the program was in an effort to attempt to silence critics of the Bush Administrationand its handling of several controversial issues during its tenure. Under public pressure, the Bush administration allegedly ceased the warrantless wiretapping program in January 2007 and returned review of surveillance to the FISA court.Subsequently, in 2008 Congress passed the FISA Amendments Act of 2008, which relaxed some of the original FISA court requirements.During the Obama Administration, the NSA has allegedly continued operating under the new FISA guidelines despite campaign promises to end warrantless wiretapping. However, in April 2009 officials at the United States Department of Justiceacknowledged that the NSA had engaged in "overcollection" of domestic communications in excess of the FISA court's authority, but claimed that the acts were unintentional and had since been rectified. 5. The Purple Heart is a United States military decoration awarded in the name of the President to those wounded or killed while serving, on or after April 5, 1917, with the U.S. military. With its forerunner, the Badge of Military Merit, which took the form of a heart made of purple cloth, the Purple Heart is the oldest military award still given to U.S. military members – the only earlier award being the obsolete Fidelity Medallion. The National Purple Heart Hall of Honor is located in New Windsor, New York.
