Trump says he's talking about the Iran war with a regretful former president.

Who might that be?

The lead starts right now.

As the war with Iran enters its third week, President Trump is criticizing U.S. allies

who say they do not want to be pulled into the conflict.

But the president also claims

there's a former U.S. president who privately praised his decision to take out the regime's leader

and saying he wishes he had done it. Plus, nearly 100 million Americans are at risk for a severe

storm today, from feet of snow to tornadoes to dangerous hail and damaging winds. We're going to go live to the CNN Weather Center for a severe storm today from feet of snow to tornadoes to dangerous hail and damaging winds.

We're going to go live to the CNN Weather Center for a brand new forecast.

And as some Democrats call for a new generation of leaders to take the helm, Congressman

Jim Clyburn says he's not going anywhere.

The 85-year-old just announced he's going to run for his 18th term in Congress.

and some are. And the level of enthusiasm matters to me.

Do you have any minesweepers?

Well, we would rather not get involved, sir.
