Habba also worked on Trump's behalf when he was sued for defamation by Summer Zervos. Trump had called Zervos a "liar" in 2017, after she accused him of kissing her and groping her, without her consent, when she was a contestant on Trump's reality TV show, The Apprentice. In October 2021, Habba filed Trump's countersuit against Zervos, claiming she was trying to stifle Trump's right to free speech. Shortly thereafter, in November 2021, Zervos dismissed the lawsuit.
