GEOFF BENNETT: New information# about the assassination attempt## on former President Donald Trump# starts the day's other headlines.

Acting Secret Service Director Ronald# Rowe said today that his agents were## not on the same radio system as local law# enforcement on the day of the shooting.## That cost valuable time when local# police warned via radio that there## was an armed assailant on the roof of a# building outside the security perimeter.

This afternoon, Rowe told reporters his# agency takes full responsibility.

It's## after he partially blamed local law enforcement# during congressional testimony earlier this week.

RONALD ROWE, Acting U.S. Secret Service# Director: This was a Secret Service failure,## and so they should not be blamed.# There was somebody who did in fact## radio out that they had seen# the individual with a weapon.

What I can tell you is that that piece of# information, that vital piece of information,## and by no fault of anyone -- it was a very# stressful situation.

It did not make it over.

GEOFF BENNETT: Rowe said he will consider# having Secret Service inside what's called## the unified command post, which# is operated by local authorities,## at all times going forward to# ensure better communication.

Turning abroad now to Venezuela's presidential# election, the Biden administration has now## officially recognized Nicolas Maduro's challenger,# that's opposition candidate Edmundo Gonzalez, as## the winner.

Other countries, including Argentina,# Ecuador and Costa Rica, have done the same.

It all comes as a fellow opposition leader,# Maria Corina Machado, said masked men## ransacked her party's headquarters overnight.# That raid follows threats by top officials,## including from Maduro himself,# that he would arrest his political## rivals.

Maduro has yet to produce# evidence of his claimed victory.

Mourners held a funeral for slain Hamas# leader Ismail Haniyeh today days after he## was assassinated in Tehran.

Attendees prayed over# Haniyeh's coffin at the National Mosque in Qatar,## where he'd lived for the last several years.# Palestinians in Jerusalem also mourned his## death.

Haniyeh was a main negotiator for# Hamas in cease-fire talks with Israel.

Last night, President Biden said the# assassination was not helpful for negotiations,## and he urged Israeli Prime Minister# Benjamin Netanyahu to act quickly.

JOE BIDEN, President of the United States:# I'm very concerned about it.

I had a very## direct meeting with the prime minister today# and very direct.

We've got a -- we have the## basis for a cease-fire.

He should move# on it, and they should move on it now.

GEOFF BENNETT: Meantime, Hezbollah# resumed a rocket and artillery fire## against Israel today.

It ended# a pause in these cross-border## strikes following Israel's killing of a top# Hezbollah commander in Beirut this week.

The leading global authority# on food security has officially## declared a famine in the Darfur region# of Sudan, where more than half-a-million## people have fled from the spiraling# violence of that country's civil war.

Special correspondent Leila Molana-Allen# has this report from inside Sudan.

LEILA MOLANA-ALLEN: I'm in Port Sudan, which# is the Sudanese government's wartime capital## after the capital Khartoum was seized last# year by the Rapid Support Forces militia.

And after weeks of dire warnings, the World# Food Program says it has found evidence## of famine in Zamzam camp in North Darfur,# where around 200,000 displaced people live,## and an immediate risk of famine in 14 other areas# of Sudan.

That means that over 20 percent of## people in those areas are at immediate risk# of starvation, malnutrition, and death.

If nothing is done by September, millions of# people in Sudan could be facing full famine,## which would be the greatest famine# of recent decades.

The Sudanese## Armed Forces and the government say# there is no famine anywhere in Sudan,## and they deny claims that they have been# stopping aid crossing posts into RSF territory.

For the PBS "News Hour," I'm# Leila Molana-Allen in Port Sudan.

GEOFF BENNETT: Today, both the U.N. and# USAID led renewed calls for a cease-fire,## so that humanitarian assistance# could get through.

Aid workers## haven't been able to get supplies to the# destitute camps in Darfur since April.

Back in the U.S., the Justice Department and# Federal Trade Commission have sued TikTok## and its parent company, ByteDance.

They# claim the social media app violates online## privacy by failing to seek parental consent before# collecting data on children under the age of 13.

In a statement, TikTok said it offers --# quote -- "age-appropriate experiences"## with stringent safeguards.

On Wall Street, the poor jobs numbers today sent# stocks into a freefall over investor concerns that## the economy could be weakening.

The Dow Jones# industrial average plummeted over 600 points,## the Nasdaq dropped by over 2 percent,# and the S&P 500 lost 100 points.

And a spoiler alert.

We have the latest# from today's action at the Paris Olympics.## One of Team USA's star sprinters, Sha'Carri# Richardson, made her first Olympic strides## today, breezing through her opening heat# of the 100 meters.

Americans also secured## a spot in the final for the 4x400 meter mixed# relay, breaking the world record along the way.

In the pool, Leon Marchand of France# extended his dominant swimming streak## with a fourth gold in front of# a home crowd.

But it's Team USA## who leads the medal count at the end# of week one, with 43 medals overall.

Still to come on the "News Hour": Jonathan# Capehart and Eliana Johnson analyze the busy week## of news at home and abroad; a new book looks at# the fascinating true story of a formerly enslaved## man who was crucial to creating Jack Daniel's# whiskey; and poetry comes to the national parks.
