Sen. David Vitter, R-La, took to Twitter to slam Senate Majority Leader Harry Reid, D-Nev., for comments he made comparing Hurricane Katrina victims to superstorm Sandy victims.

"Sadly, Harry Reid has again revealed himself to be an idiot, this time gravely insulting Gulf Coast residents," Vitter wrote today.

He's referring to comments Reid made on the floor of the Senate Friday where expressed disbelief for how long it took for Congress to approve federal disaster relief for New York and New Jersey. He said the people affected by Katrina in 2005 were impacted, "but nothing in comparison" to those impacted by Sandy. Katrina killed over 1,800 people and caused $145 billion in damage; 120 died after Sandy hit and the storm caused an estimated $80 billion in damage.
