US ‘making progress’ in Iran talks, US vice president says

US ‘making progress’ in Iran talks, US vice president says US Vice President JD Vance says he believes progress is being made in negotiations with Iran after President Donald Trump rejected Tehran’s latest proposal as unacceptable. “I think that we are making progress. The fundamental question is do we make enough progress that we satisfy the president’s red line?” Vance told reporters at the White House.
