In 1998, Deputy Assistant Army Secretary Michael L. Davis tried to stop the Army Corps of Engineers from rubber-stamping casino applications without studying the impact dredging would have on marshes that shelter wildlife, purify drinking water and help prevent flooding. This angered Lott, then Senate majority leader, who had recently flown to Las Vegas in a casino executive's jet and had raised $100,000 for Republicans at a casino-industry fundraiser.
Lott got the moratorium lifted, then he got the Army to launch an investigation of Davis. No wrongdoing was found, but Davis was removed from Gulf Coast permitting issues.
