Trump threatens to sue over 'nasty' campaign ads
Speaking at a rally in Henderson, Nev., the GOP presidential nominee insisted he would help veterans if elected and complained that he was unfairly targeted by negative advertising.
“And then I saw today ... a commercial where — it was really a nasty commercial, totally made up, about me with vets,” Trump said. 
“There is nobody that loves the vets more or respects the vets more. They’re spending hundreds of millions of dollars on false commercials, and it’s a disgrace. So what we’ll do, I guess we’ll sue them. Let’s sue them.”
It was not immediately clear which ad Trump was referring to.
At last week’s first presidential debate, Trump complained that Democratic nominee Hillary ClintonHillary Diane Rodham ClintonDemocratic groups using Bloomberg money to launch M in Spanish language ads in Florida The Hill's Campaign Report: Presidential polls tighten weeks out from Election Day More than 50 Latino faith leaders endorse Biden MORE runs “very nasty commercials that you do on me in so many different ways, which I don't do on you.”
He did not make clear at the time which ads he was referring to. Many of Clinton’s attack ads use footage of Trump speaking.
