Tea party-backed U.S. Sen. Ted Cruz and Republican gubernatorial hopeful, Texas Attorney General Greg Abbott will tour facilities housing unaccompanied minors Monday at San Antonio's Lackland Air Force Base.

Later, Gov. Rick Perry will visit a federal facility for unaccompanied minors in the border town of Weslaco. He will also be briefed by federal officials and state officials there.

Perry has authorized spending an extra $1.3 million a week in border security amid what he calls a "humanitarian crisis."
