Nikki Haley, the US ambassador to the United Nations, said in a statement: "The Iranian government is being tested by its own citizens. We pray that freedom and human rights will carry the day."The protests, which initially focused on economic hardships but now include anti-government messages, appeared to resume for a fourth day on Sunday despite Tehran's warnings of a crackdown and restrictions on messaging apps used by the demonstrators. The protests are the biggest since unrest in 2009 that followed the disputed re-election of then-President Mahmoud Ahmadinejad.US Senator Lindsey Graham, a South Carolina Republican, said Trump should give a nationwide address, laying out the terms of an improved nuclear agreement with Iran."President Trump is tweeting - very sympathetically to the Iranian people," Graham said on CBS News' Face the Nation program. "But you just can't tweet here. You have to lay out a plan." On the same program, Republic Representative Will Hurd of Texas said the United States should support peaceful protests in Iran.If Iran cracks down, he said, "that's where we should be talking about sanctions because these are human rights abuses."Big protests in Iran. The people are finally getting wise as to how their money and wealth is being stolen and squandered on terrorism. Looks like they will not take it any longer. The USA is watching very closely for human rights violations!
