Supreme Court Begins Hearing Amnesty Case:  Supreme Court justices will begin hearing their biggest case of the term Monday morning to consider whether President Obama overstepped his constitutional powers when he granted a tentative  amnesty to five million illegal immigrants.  Stephen Dinan of the Washington Times reports that Obama first announced his deportation policy in November, the objective of which is to grant nearly half of the 11 million illegal immigrants in the U.S. a proactive stay of deportation, allowing them access to work permits, driver's licenses, Social Security numbers and some taxpayer benefits.  The policy prompted 26 states to sue, arguing that the amnesty caused economic harm.  The states, led by Texas, also argue that President Obama broke administrative law and immigration law, and violated the Constitution, when he strayed too far from the Take Care Clause, writing law rather than simply carrying it out.  The amnesty has been halted by lower courts on statutory grounds until justices decide.  The justices are expected to make a ruling by the end of June.

Another Record-Breaking Year Expected in Alien Children Surge:  Unaccompanied alien children apprehended on the U.S. border has surged more than 1,200% since 2011 with no end in sight as the flow increased significantly in the first five months of FY 2016.  Adam Kredo of the Free Beacon reports that a Congressional Research Service report shows that in the first five months of 2016, nearly 20,000 illegal immigrants children -- mostly from El Salvador, Honduras and Guatemala -- were apprehended at the border, "setting the state for another potentially record-breaking year."  Experts warn that illegal immigrant children will continue to surge into the country so long as the United States' immigration policy is viewed as advantageous to illegal immigrants.

Urgency in CA to Find Roadside Test for Drugged Drivers:  As California moves closer toward legalization of adult recreational marijuana use, there is a new urgency in the state to find a "practical and reliable" field test to determine when a driver is under the influence of marijuana.  Brooke Edwards Staggs of the LA Daily News reports that California Sen. Bob Huff has proposed Senate Bill 1492, which would authorize use of saliva swab tests to help police officers detect for the presence of marijuana and other drugs.  Critics argue that the proposed device is still "too experimental and unreliable to be put into wider use" and isn't even effective at testing the two types of drugs most frequently encountered, marijuana and prescription medicines.  The state is partnering with UC San Diego's Center for Medical Cannabis Research Center to conduct research, beginning the fall, to study how marijuana impacts motor skills.
