Facebook said Thursday that it had ended its relationship with a Washington-based consulting firm, Definers Public Affairs, which spread disparaging information about the social network’s critics and competitors.

Definers was founded by veterans of Republican presidential campaigns and specialized in applying political campaign tactics to corporate public relations.
