have grown to over names and to be continually expanding. However, according to Homeland Security secretary Michael Chertoff, in October 2008 the No Fly List contained only names, with an additional "selectees" who "represent a less specific security threat and receive extra scrutiny, but are allowed to fly." As of 2011, the list contained about 10,000 names. In 2012, the list more than doubled in size, to about 21,000 names. In August 2013, a leak revealed that more than 47,000 people were on the list. In 2016, California Senator Dianne Feinstein disclosed that 81,000 people were on the No Fly List. There is a huge, secretive US anti-terrorism database for Canada specifically, "Tuscan" (Tipoff US/Canada), revealed by Canada's access to information system. The database is used by both the US and Canada, and applies to all borders, not just airports. It is believed to contain information on about 680,000 people thought to be linked with terrorism. The list was created in 1997 as a consular aid. It was repurposed and expanded after 9/11, and again in 2016. The names in Tuscan come from the US Terrorist Identities Datamart Environment (Tide), which is vetted by the FBI's Terrorist Screening Center and populates various US traveller databases, Canada's Tuscan and the Australian equivalent, "Tactics". Weapons purchases by listed persons (No Fly No Buy) In a 2010 report, the Government Accountability Office noted that "Membership in a terrorist organization does not prohibit a person from possessing firearms or explosives under current federal law," and individuals on the No Fly List are not barred from purchasing guns. According to GAO data, between 2004 and 2010, people on terrorism watch lists—including the No Fly List as well as other separate lists—attempted to buy guns and explosives more than 1,400 times, and succeeded 1,321 times (more than 90% of cases). Senator Frank Lautenberg of New Jersey repeatedly introduced legislation to bar individuals on the terror watch lists (such as the No Fly List) from buying firearms or explosives, but these efforts have not succeeded. Senator Dianne Feinstein of California revived the legislation after the November 2015 Paris attacks and President Barack Obama has called for such legislation to be approved. Republicans in Congress such as Senate Homeland Security Committee chair Ron Johnson and former Speaker of the House Paul Ryan oppose this measure, citing due process concerns and efficacy, respectively. Republicans have blocked attempts by Democrats
