Fence

The Secure Fence Act of 2006 authorized 700 miles of border wall and about 500 miles have been built. The act also authorized the use of more vehicle barriers, checkpoints and lighting to curb illegal immigration, and the use of advanced technology such as satellites and unmanned aerial vehicles. Obama, Clinton, Schumer and 23 other Democratic senators voted in favor of the act when it passed in the Senate by a vote of 80 to 19. "We saw a 203 percent increase from March 2017 compared to March 2018 and a 37 percent increase from last month to this month — the largest increase from month to month since 2011," Tyler Houlton, the DHS press secretary, said in a statement.
