President Donald Trump said on Sunday he did not care whether Iran agreed to negotiate with the United States, APA reports.
Earlier, White House National Security Adviser Robert O'Brien said that the "maximum pressure" campaign on Iran by strangling it with sanctions had been effective enough and would eventually press Tehran to negotiate.
"I think the maximum pressure campaign is working. Iran is being choked off, and Iran is going to have no other choice but to come to the table", O'Brien told Fox News Sunday.
