For President Barack Obama, the humanitarian crisis at the U.S.-Mexico border is increasingly becoming a political liability, giving Republicans a fresh opportunity to question his administration's competence and complicating the debate over the nation's fractured immigration laws.

Still, Obama is resisting calls to visit the border during his two-day fundraising trip to Texas, where he arrives late Wednesday afternoon. Instead, Obama will hold a meeting hundreds of miles away in Dallas to discuss the crisis with faith leaders and Texas officials, including Republican Gov. Rick Perry.

Obama's trip comes one day after he asked Congress for $3.7 billion in emergency spending to get more resources to the border.

The roundtable discussion in Dallas is seen by the White House as a way to address the immigration issue while avoiding awkward optics at the border. Tens of thousands of unaccompanied children have arrived there in recent months, many fleeing violence in Central America, but also drawn by rumors that they can stay in the U.S. White House officials say most are unlikely to qualify for humanitarian relief and will be sent back to their home countries.

Obama's decision to skip a border visit is likely to provide more fodder for the Republicans and the handful of Democrats who say the president hasn't responded quickly and forcefully enough to the mounting crisis.
