From the opinion pages of the Wall Street Journal, this is Potomac Watch.

A shooting at the White House Correspondence Dinner on Saturday evening in Washington, D.C.

raises questions about security for the American president and about political violence in the United States.

Plus Britain's King Charles visits the U.S. and a much anticipated state visit to Washington,

complete with all of the pomp and circumstance that Donald Trump can muster.

Can the British monarch help repair the fraying relations between the two long-time allies?

Welcome.

Those are our subjects for today.

I'm Potomac Watch.

I'm Paul Giego with the Wall Street Journal Opinion Pages.

And I'm here with my colleagues, Joe Sternberg, London-based, expert on the Brits, and Kim Strassel, expert on the Americans. So welcome to you both. Let's talk

about the assault by Cole Allen, the 31-year-old teacher from Torrance, California, who is a suspected

shooter. He charged through the security perimeter at the Washington Hilton Hotel, where the president,

First Lady, various cabinet officials and some 2,500 journalists were assembled for their annual

gala. Alan was subdued by law enforcement before he entered the ballroom, but not before he shot

a member of the Secret Service,

who was protected by the president, says a bulletproof vest. But the assault did force the

evacuation of the president, the vice president, and others, and ultimately the cancellation

of the event. Let's listen to the president talk about the event on 60 minutes on Sunday.

I wasn't worried. I understand life. We live in a crazy world. You can really enhance your chances of having a perfect situation, but sometimes things will happen.

I did want to see what was happening because, you know, the president.

In one way, I guess I should be hiding.
