Hello everyone and welcome to Amunpur. Here's what's coming up.

Mourners from around the world pay respects to Pope Francis, who's now lying in state at St. Peter's Basilica at the Vatican.

The former Irish President, Mary McAleese, on the importance of continuing Francis's church reforms

and her own personal fight for progress. Plus, Trump does another U-turn to calm markets and people

spooked by his trade war. Former Obama advisor David Axelrod here in London is getting an earful

wherever he goes.

Then, Pope Francis' extraordinary relationship with a small church inside Gaza.

Jeremy Diamond reports on the daily phone calls that kept up wartime morale.

Plus, Trump's fight against anti-Semitism has become fraught for many Jews.

Those are the words of Rabbi Sharon Browse, who joins me to discuss America's crackdown on higher education. Welcome to the program, everyone, I'm Christian Amunpur in London.

Pope Francis will now lie in

state at St. Peter's Basilica until his funeral on Saturday. Crowds of flocking to pay their respects,

and this marks a pivotal moment for the Catholic Church to continue Pope Francis reforms or revert to strict pre-Francist

traditionalism. U.S. President Donald Trump says he and the First Lady will go to the funeral announcing,

we look forward to being there.

The event may become more than just a farewell to the Pope,

as assembled world leaders have a lot to discuss with the U.S. President.

Trump's strongman-winner-take-all attitude is in stark contrast, of course, to Pope Francis,

who was driven by compassion for the weakest, the poorest, the most vulnerable in society.

And he is a native of Argentina. He's ordered seven days of mourning following the pontiff's

passing. That is, the president of Argentina has done that. CNN's David Culver is there touring through the Pope's childhood neighborhood

and speaking to some of his longtime friends.
