Democratic lawmakers from the region say too little is being done to contain the worst ecological disaster caused by an oil spill in U.S. history.
"Everything that I know and love is at risk," an emotional Rep. Charlie Melancon, D-La., said Thursday. "Even though this marsh lies along coastal Louisiana, these are America's wetlands."
Plaquemines Parish president Billy Nungesser has been a vocal critic of the federal government's response to the oil disaster, even calling Allen a "national embarrassment."
"I want him [Obama] to say that they're doing everything physically possible to keep this oil from destroying our wetlands," Nungesser, who is based in Venice, Louisiana, said on "GMA" today. "That's all we've been asking for from the beginning.
"I don't think the president knew what was really going on."
