(LA TIMES) The nation’s top Homeland Security official portrayed himself Tuesday as a steward of President Trump’s vision for border security as he laid out a path to fruition for some of Trump’s most bombastic campaign promises.

In his first appearance on Capitol Hill, Homeland Security Secretary John F. Kelly described plans for safeguards along the border that were more piecemeal than the “big, beautiful wall” Trump has touted.

Kelly said his agency would first build sections of wall and fencing where border agents see an immediate need and fill in gaps with ground sensors, surveillance blimps and other technologies that help detect illegal border crossings, emphasizing that the government lives in “a world of finite time [and] resources.”
