Amna Nawaz: We start the day’s other headlines# with the impact of President Trump’s tariffs.

The## nation’s largest retailer, Walmart, is planning# to raise prices in the coming weeks, citing## Trump’s policies as a driving factor.

Walmart’s# head said today “given the magnitude of the## tariffs.we aren’t able to absorb all the pressure# given the reality of narrow retail margins” Walmart posted strong quarterly sales today,# but declined to give a profit outlook due to## economic uncertainty.

In the meantime, consumers# are growing increasingly uneasy.

New government## data shows that the pace of retail sales# slowed sharply in April from the month before.

A judge in Wisconsin pleaded not# guilty today to federal charges## over accusations she helped a man# evade federal immigration agents.

Milwaukee county circuit judge Hannah Dugan# allegedly escorted the person out the back door## of her courtroom last month as agents sought# his arrest for being in the US illegally.

Man: Get angry, get loud!

Amna Nawaz: Dozens of demonstrators gathered# outside the courthouse ahead of today's hearing.

Dugan's arrest has been a flashpoint in# the broader tensions over President Trump's## sweeping immigration crackdown.

She could# face up to six years in prison if convicted.

A federal judge has dismissed charges against# dozens of migrants who had been detained for## trespassing in a newly-designated militari... at the southern border.

The Trump administration## recently transferred oversight of a 180-mile strip# of land in New Mexico to the military.

Entering## the area unauthorized carries a potential# sentence of at least a year in prison.

But today, a U.S. district court judge ruled# the government had provided “no facts from## which one could reasonably conclude that the# defendant knew he was entering” the zone.

The migrants could still face other# misdemeanor charges and deportation.

It all comes on the anniversary of the "nakba"# -- arabic for "catastrophe" -- when, in 1948,## hundreds of thousands of Palestinians were# forcibly displaced from what is now Israel.

One woman who lived through that experience# says today's violence is even worse.

Ghalia Abu Moteir, displaced Palestinian# (through interpreter): Today, we’re in a## bigger nakba than the nakba we saw before.#.. no children, no people, no food or drink.

How long## must we remain like this?

Where can we go?

Amna Nawaz: Today, U.S. Secretary of State## Marco Rubio told reporters he is troubled# by the humanitarian situation in Gaza.

He also spoke with Israeli prime# minister Benjamin Netanyahu -- who,## earlier this week, vowed to 'complete# the mission" by 'destroying Hamas".

Back here at home-Florida Governor Ron DeSantis# signed a measure today that blocks local## governments in the state from adding fluoride to# their water.

During a bill signing event in Dade## City, DeSantis said that forcing the mineral into# the water supply is "basically forced medication".

Florida is now the second state to implement such# a ban, after Utah.

State lawmakers approved the## bill last month, despite concerns from# dentists and public health advocates,## who say it could have long-lasting health# consequences.

Florida's ban takes effect July 1st.

On Wall Street today, stocks drifted a# bit following the latest economic reports.

The Dow Jones industrial average added about 270## points on the day.

One of the architects of America's hydrogen bomb# has died.

Richard Garwin was only 23 when he built## the world's first fusion bomb.

He later advocated# for arms control, worked on early technologies## that led to things like touch-screen monitors, and# advised presidents from Eisenhower to Obama.

In the fall of 2016, it was Obama --# who awarded him the medal of freedom,## the nation's highest civilian award.

Richard Garwin was 97 years old.

And, a discovery of note: historians# at Harvard University say a document## in their archives -- long believed to be a# copy of the Magna Carta -- is actually one## of the earliest versions of the medieval# text... dating back to the year 1300.

The university purchased the tattered# piece of parchment in 1946 for less than## $30 dollars -- which would be about 500 dollars# today.

it was wrongly cataloged at the time.

After## coming across it on the law school library's# website, professors noticed the smallest of## details -- certain letters capitalized, quirks# in penmanship, and realized what they had found.

David Carpenter, Professor, King’s College# London: They bought it for peanuts,## in 1946 from an auctioneer Sweet and Maxwell, who# equally seemed to have no idea what it was-Harvard## Law School had indeed, unbeknownst to them,# got an original of the 1300 Magna Carta.

An## original therefore, of one of the most famous# documents in world constitutional history.

Amna Nawaz: until now, there# were only six known editions## of the 1300 Magna Carta -- issued# by britain's King Edward the First.

The document was first issued in 1215, and# established the principle of "the law of## the land", which influenced the framers of# the U.S. constitution, among many others.

Harvard estimates their version is worth millions# of dollars -- but has no plans to sell it.
