SAN DIEGO (AP) — The Trump administration is waiving federal contracting laws to speed construction of a U.S.-Mexico border wall, moving the president closer to fulfilling a signature campaign promise in an election year but sparking criticism about potential for fraud, waste and abuse. The Department of Homeland Security said Tuesday it'll allow 177 miles of wall to be built faster in California, Arizona, New Mexico and Texas. A 2005 law gives the Homeland Security secretary sweeping powers to waive laws to expedite border barrier construction.
