WASHINGTON, March 30 (UPI) -- U.S. President Barack Obama will travel to Colorado next week to promote legislation intended to reduce gun violence, the White House said Saturday. The president will meet with local law enforcement officials and community leaders to discuss newly enacted Colorado laws, including laws to close background check system loopholes, the White House said. He plans to deliver an address on the subject at the Denver Police Academy. Obama called on Congress Thursday to act on gun control. Speaking in the White House East Room, the president recalled the 26 children and adults killed by a gunman at Sandy Hook Elementary School in Newtown, Conn., Dec. 14. "It's been barely 100 days since 20 innocent children and six brave educators were taken from us by gun violence -- including Grace McDonnell and Lauren Rousseau and Jesse Lewis, whose families are here today," he said.
