PILF meaning in Governmental ?

The Public Interest Legal Foundation (PILF) is an American conservative legal group based in Indianapolis, Indiana, which is known for suing states and local governments to purge voters from election rolls. The nonprofit was constituted in 2012.

PILF asserts that "large numbers of ineligible aliens are registering to vote and casting ballots", although lists that they have displayed of such supposed voters prove to actually include American natives who are eligible voters. PILF said its lists had been based on state government lists of declared “non-citizens” removed from local voter rolls, but some U.S. citizens were wrongfully purged in the process. The group has made false claims about the extent of voter fraud in the United States, and the organization has published the information of eligible voters online, including Social Security numbers, falsely accusing them of being fraudulent voters.
