LAS VEGAS (AP) — A trio of Republican senators is sounding the alarm about billions in looming military budget cuts on tap for January, stopping their tour Monday at a Nevada Air Force base and the city of North Las Vegas.

Arizona Sen. John McCain, South Carolina's Lindsey Graham and New Hampshire's Kelly Ayotte are visiting Nellis Air Force Base before taking their "Preserving America's Strength" town hall to a nearby community college Monday afternoon, condemning a planned budget sequester that would impose $110 billion in federal spending cuts Jan. 2.

"President Obama's own secretary of defense called the looming defense cuts under budget sequestration 'devastating,' likening them to 'shooting ourselves in the head,' and yet to date, Congress and the Obama Administration have done nothing to stop them from going into effect," the senators said in a statement.
