Welcome to meet the press now. I'm Kelly O'Donnell in Washington, and here we go again with President Trump renewing his threat to obliterate Iran's civilian infrastructure.

New uncertainty over peace talks, tensions skyrocketing over the Strait of Hormuz, energy prices

moving higher, and new public backlash against the war. Right now, Vice President Vance,

along with special envoy Steve Whitkoff and the president's son-in-law, Jared Kushner,

are likely to travel to Islamabad tomorrow for a second round of negotiations with Iran.

That's according to sources familiar with the matter.

But Iran's foreign ministry says no decisions have been made about whether its side will attend

those talks.

Yesterday, President Trump ramping up pressure on Tehran to come to the table, writing on

social media, quote, no more Mr. Nice Guy, and once again threatening to knock out every single

power plant and every single bridge in Iran if it doesn't agree to a deal by Wednesday.

The president also announcing over the weekend that the U.S. Navy seized an Iranian-flagged cargo

ship, it says, was attempting to breach the U.S. blockade of Iranian ports.

The Pentagon releasing this video of the Navy's warning to that Iranian vessel.

Motor vessel tovostovostov. Motov tovostka, vacate your engineer, vacate your engineer.

We're prepared to subject you to disabling fire.

In response, Iran accused the U.S. of violating the ceasefire and vowed to retaliate against what it called an active armed piracy and theft by the U.S. military.

Yesterday on Meet the Press, UN Ambassador Mike Walts insisted the president will not back down.

If there is no deal by Wednesday, will the president extend the ceasefire agreement?

Well, that's ultimately a decision for the president. And I'm certainly not going to negotiate on

national television. Understood, but is it on the table? Is it on the table? Is it on the table? Is that

possibility on the table? Everything's on the table? Is that possibility on the table?
