"The catastrophic nature" of the oil disaster, "I still believe, is not fully known to us," New Orleans, Louisiana, Mayor Mitch Landrieu told CNN Monday. "It's really huge."
As far as the federal response, "it's never good enough. It's never fast enough," he said, adding he thinks the federal government turned a corner last week as far as getting people on the ground.
"There is no quick fix here," Landrieu said, "and I think people need to kind of get focused on that fact." He said he does not believe the underwater oil gusher will be stopped until a relief well under construction is complete in August.
