A courtroom showdown between the National Rifle Association and New York prosecutors is expected to get underway Monday, with the state arguing that top officials at the once-powerful lobbying group were corrupt and used money coming in from members as a “personal piggy bank.” 

The civil corruption trial comes just days after the resignation of longtime leader Wayne LaPierre, who told NRA board members Friday he would be stepping down from the chief executive post he’s held for more than three decades.
