After Congress rejected President Trump's request for 5.7 billion dollars for the border wall, the president declared a national emergency at the southern border. Present Trump claims this "emergency" gives him the authority to divert funds appropriated for other purposes to building the border wall.
President Trump's emergency declaration is not just an end run around Congress. It is an end run around the Constitution. Article One of the Constitution gives Congress sole authority to allocate federal funds.
While President Trump's order may be a particularly blatant abuse of power, it is hardly unprecedented. Most modern presidents have routinely used so-called national emergencies to expand their power, often at the expense of liberty. For example, Present Franklin Delano Roosevelt used "emergency powers" to justify internment of Japanese-Americans during World War Two.
President Trump, like other recent presidents, is relying on the 1976 National Emergencies Act for legal justification for his emergency declaration. This act gives the president broad powers to declare national emergencies for almost any reason. All the president need do is inform Congress he has declared an emergency. Once the emergency is declared, the president simply needs to renew the declaration once a year to maintain a state of emergency. Since this act passed, 59 emergency declarations have been issued, with 31 of those still in effect.
Another statute giving the president broad "emergency" powers is the Defense Production Act. Under this law, the president can force private businesses to produce goods for the military. The law also enables the president to impose wage and price controls and even make loans to private businesses. All a president need do to invoke these vast powers is submit "findings" to Congress that "national security" requires the president seize near-dictatorial control of certain industries or even the entire economy. According to the Congressional Research Service, some presidents have invoked the Defense Production Act without making the required findings to Congress, and the act has been used to justly federal interference in areas having little or nothing to do with national defense.
Section 606(c) of the Communications Act gives the president "emergency" power to seize control of every television network, radio station, smartphone, laptop, and other electronic devices.
Emergency powers are not the only means by which presidents violate the Constitution. The 2001 authorization for use of military force (AUMF), which only authorizes the president to use force against those responsible for the September 11 attacks, has been used to justify military interventions that have no relationship to those attacks. The 2001 AUMF has been used to justify mass surveillance, indefinite detention, and even "kill lists." Fortunately, Representative John Garamendi has introduced the Walter B. Jones Restoring Power to Congress Act that would pay tribute to a true champion of peace by repealing the 2001 AUMF.
