 "CNN" noted that Heller had "aligned himself closely" with Trump after the President in 2017 threatened to support a primary challenge against him.Following the threat, Heller flip-flopped on health care (ultimately supporting a conservative bill to repeal the Affordable Care Act), supported Trump's immigration reform proposal, and avoided direct criticism of Trump for several months.In March 2018, Trump endorsed Heller in his Senate bid, convincing primary challenger Danny Tarkanian to drop out of the race.
