Seattle Mayor Ed Murray says sex abuse allegations made against him "were very painful" but that he won't back down in fighting them.
In a brief statement Friday, Murray said "the individual making these allegations is troubled, and that makes me sad as well."
Murray, who is running for re-election, said he has never backed down, and "I will not back down now."
Murray didn't take questions, saying the lawsuit is a legal matter that will be addressed in the court.
A lawsuit filed Thursday by a man identified only by initials had accused Murray of sex abuse of a then-teenage boy in the 1980s. Murray had previously denied the allegations through a spokesman, saying they are politically motivated.
