President Barack Obama casually pressured the Republican-controlled Congress to address the medium- and long-term financial needs of flood-ravaged Louisiana as they arise Tuesday, as GOP members of the state's congressional delegation stood behind him.

Obama, who said he wasn't worried about political appearances with just five months remaining in his term, predicted that the House and Senate "may be called upon to do some more [funding]" once the exact needs on the ground are determined. For now, existing law and Federal Emergency Management Agency dollars are enough, but they might not be down the road, the president said.

"Now, the good news is, you've got four members of Congress right here, and a number of them happen to be in the majority," Obama said, pointing his thumb over his shoulder at Sens. Bill Cassidy and David Vitter, both Republicans. "So, I suspect they may be able to talk to [House speaker Paul Ryan] and talk to Mitch McConnell."

GOP lawmakers have reacted to certain disaster relief efforts with skepticism in the recent past. Nearly 180 House Republicans voted against a $50 billion package for Hurricane Sandy in 2013, for example, which they criticized for containing extraneous and unnecessary funds.

There's no such fight brewing over the Louisiana response at the moment—and despite the president's warning, that moment might never come. The administration issued a disaster declaration August 14, and FEMA has conveyed confidence that it has enough money for response efforts. "Congress has appropriated the necessary funding to address disasters for this fiscal year. FEMA has enough funding to address response and recovery support to Louisiana," an agency spokesman told Roll Call.

FEMA's disaster recovery fund totaled $3.78 billion at the beginning of August. The fiscal year concludes September 30.

While the level of federal assistance requested for Louisiana is to be determined, Obama added Tuesday that the public shouldn't turn its eye from the state as it rebuilds, seeming to take a shot at critics who had admonished him for not visiting the flooded areas sooner in the process.

"Let me just remind folks: Sometimes, once the flood waters pass, people's attention spans pass. This is not a one-off. This is not a photo-op issue," Obama said. "This is how you make sure that a month from now, three months from now, six months from now, people still are getting the help that they need. I need all Americans to stay focused on this."
