They understand that. I have no choice,” Trump said. Speaking in an interview with Fox News, he said that there was an “all-day negotiation” with Tehran on Tuesday (Aug 4), and that both countries were having “very good” discussions, adding that his first choice was pushing for a diplomatic agreement.
