President Barack Obama waves as he walks to Marine One on the South Lawn of the White House in Washington, Tuesday, Aug. 23, 2016, for a short trip to Andrews Air Force Base, Md., then onto Baton Rouge, La., where he will get a first-hand look at the impact of recent devastating floods.

Obama didn't cut his vacation on Martha's Vineyard short to make the trip, and the images of him playing golf while water rescues continued weren't well-received.
Trump visited Louisiana last week, though his campaign reportedly hadn't notified Democratic Gov. John Bel Edwards. Edwards warned Trump not to use the trip as a photo opportunity.
Trump and his campaign did appear to help in relief efforts and made a donation, and Edwards praised him in return.
Edwards told CNN he asked the president to hold off on visiting.
"I didn't want to divert these police officers, sheriff's deputies and state troopers and other essential resources and assets to providing security for the president while they were needed in this region," Edwards said.
That's said to be the same reason President George W. Bush flew over New Orleans after Hurricane Katrina instead of stopping there on his way back to the White House from his vacation. Unlike Obama, Bush did cut his vacation short, though he was still heavily criticized for a slow response.
Hurricane Katrina hit Aug. 29, 2005. Bush flew back to Washington, D.C., on Aug. 31. He traveled to the Gulf Coast on Sept. 2.
One adviser told The Washington Post that Coast Guard helicopters would have been needed to make a stop possible. He said, "Those same helicopters ... would have been pulling people off rooftops."
Nearly 2,000 people died in Hurricane Katrina. By comparison, 13 have died in the most recent Louisiana flooding.
As The Washington Post points out, it's not uncommon for a president to hold off on visiting a devastated area.
At the mayor's request, Obama held off on visiting New York City for about two weeks following Hurricane Sandy. He visited New Jersey two days after the hurricane hit.
Obama waited nearly a week to visit Moore, Oklahoma, after a tornado killed 24 people in 2013.
An explosion on the Deep Water Horizon oil rig in the Gulf of Mexico on April 20, 2010, led to the nation's worst oil spill. It took days for experts to realize the extent of the leak. Obama first visited the region about two weeks later.
So yes, the president has waited longer to visit Louisiana than he has other areas hit by disasters, but not that much longer.
