US President Barack Obama is making his first visit to flood-ravaged southern Louisiana today as he attempts to assure those who have suffered damage to their homes, schools and businesses that his administration has made their recovery a priority.
Mr Obama took some criticism by opting to complete his family's two-week vacation in Massachusetts before inspecting the flood damage personally and meeting with local residents in Baton Rouge.
An editorial headline in the Baton Rouge Advocate last week read: "Our Views: Vacation or not, a hurting Louisiana needs you now, President Obama."
The White House said Mr Obama is willing to assume criticism about "optics" as long as the federal response is up to par.
"The survivors of the flooding in Louisiana are not well-served by a political discussion; they're well-served by a competent, effective, strong, co-ordinated government response," White House spokesman Josh Earnest said.
"The federal government has certainly done our part in the first eight to 10 days after this disaster, but there's a long road ahead."
GOP presidential nominee Donald Trump visited Baton Rouge on Friday, hugging victims and driving through some of the hardest-hit areas, where the entire contents of homes were piled on the curb.
Democratic nominee Hillary Clinton issued a statement today saying she would visit the communities affected by the flooding "at a time when the presence of a political campaign will not disrupt the response, to discuss how we can and will rebuild together".
The storm and its flooding have damaged an estimated 60,000 homes and forced thousands to seek temporary housing.
More than 106,000 people have registered for federal disaster aid, with the state saying US$20m has been distributed to individuals so far. At least 40 highways remain closed.
Nearly 11 years ago, Hurricane Katrina's crippling of New Orleans and the coasts of Mississippi and Alabama demonstrated how political leaders cannot afford to underestimate the gravity of responding to natural disasters with force and immediacy.
In 2005, then-President George W Bush was faulted by critics for flying over but not touching down in Louisiana in the immediate aftermath of the hurricane, a decision he years later described as a mistake.
In 2012, Mr Obama and GOP presidential nominee Mitt Romney wasted no time in heading to Louisiana to see the damage from Hurricane Isaac.
The White House on Monday pointed to praise for the federal government from the state's Democratic governor and Republican lieutenant governor as evidence of an effective response.
It dismissed criticism of Mr Obama's decision to stay away during the first week-and-a-half after the flooding as politically motivated.
Governor John Bel Edwards, a Democrat who took office this year, said he suggested to Mr Obama and presidential adviser Valerie Jarrett that they delay a trip to Louisiana until the initial disaster response was over and recovery efforts had started.
Mr Obama signed a disaster declaration on August 14 that makes federal funding available for assistance such as grants for temporary housing and home repairs, and low-cost loans to cover losses for uninsured property.
