evidence: Senator Lindsey Graham, a South Carolina Republican, on Sunday poured cold water on former President Donald Trump's new campaign promise that would require either the government or insurance companies to cover the costs of in vitro fertilization (IVF) treatments. [...] In a Sunday appearance on ABC News' This Week, when asked by host Jonathan Karl if Graham, a Trump ally, wouldn't support "mandating insurance companies to cover" the cost of IVF, the senator said he would, but added that he instead believes in a tax credit for children. [...] Newsweek has reached out to Graham's office and Trump's campaign via email for comment.
