Prosecutors in Derek Chauvin’s murder trial have called Dr Martin Tobin, an expert in critical care and pulmonology, to give his opinion on George Floyd’s cause of death.
Tobin told the jury, “Mr Floyd died from a low-level of oxygen and this caused damage to his brain … and it also caused a [pulseless electrical activity] arrhythmia that caused his heart to stop.”
“The cause of the low-level of oxygen was shallow breathing, small breaths … shallow breaths that weren’t able to carry the air through his lungs down to the essential areas [in] his lungs,” Tobin said in response to further questions, noting shortly thereafter: “There are a number of forces that led to the size of his breath became so small.”
When asked what those forces are, Tobin’s answer pointed directly at the officers’ physical restraint of Floyd.
“He’s turned prone on the street, that he has the handcuffs in place combined with the street, and then that he has a knee on his neck, and that he has a knee on his back,” Tobin said.

Joe Biden’s gun policy event today will also be attended by survivors of mass shootings and family members who lost loved ones to gun violence.
Fred Guttenberg, a gun control advocate whose daughter Jaime died in the 2018 Parkland shooting, will be among those in attendance.
“Today is a big day,” Guttenberg said on Twitter. “Today is the day when gun safety begins. I am at the @WhiteHouse to hear @POTUS make history. Jaime, we are going to do this.”
The tweet included a selfie of Guttenberg outside the White House gates, wearing an orange mask. The color orange is associated with the gun violence prevention movement.

Calls are mounting for the Biden administration to set up a national tracking system of Covid-19 deaths among frontline healthcare workers to honor the thousands of nurses, doctors and support staff who have died and ensure that future generations are not forced to make the same ultimate – and in many cases needless – sacrifice.
Health policy experts and union leaders are pressing the White House to move quickly to fill the gaping hole left by the Trump administration through its failure to create an accurate count of Covid deaths among frontline staff. The absence of reliable federal data exacerbated critical problems such as shortages of personal protective equipment (PPE) that left many workers exposed, with fatal results.
In the absence of federal action, Lost on the Frontline, a joint project between the Guardian and Kaiser Health News (KHN), has compiled the most comprehensive account of healthcare worker deaths in the nation. It has recorded 3,607 lost lives in the first year of the pandemic, with nurses, healthcare support staff and doctors, as well as workers under 60 and people of color affected in tragically high numbers.

Zenei Triunfo-Cortez, a president of National Nurses United, the largest body of registered nurses in the US, said it was unconscionable how many healthcare workers have died from Covid. The KHN/Guardian interactive found that almost third of those who died were nurses – the largest single occupation followed by support staff (20%) and physicians (17%).
Triunfo-Cortez said the death toll was an unacceptable tragedy aggravated by the lack of federal data which made identifying problem areas more difficult. “We as nurses do not deserve this – we signed up to take care of patients, we did not sign up to die,” she said.

Number of unaccompanied children arriving at southern border hits record high
The number of unaccompanied migrant children arriving at the US-Mexican border hit a record high last month, the US Customs and Border Protection agency said today.
According to CBP’s newly released figures, 18,890 unaccompanied children arrived at the southern border in March, representing a 100% increase from February.
That number is well above the previous records of 11,475 in May 2019 and 10,620 in June 2014.

“CBP has experienced an increase in encounters and arrests. This is not new. Encounters have continued to increase since April 2020, and our past experiences have helped us be better prepared for the challenges we face this year,” Troy Miller, the acting CBP commissioner, said in a statement.
“We are committed to balancing the need to maintain border security, care for those in our custody, and keep the American people and our workforce safe.”
The news comes as Joe Biden has faced criticism from Republicans over his handling of the border, even as the president and his top aides have repeatedly stressed now is not the time to come to the US.
That criticism intensified late last month, after a Democratic congressman released photos showing an overcrowded immigration facility in Texas. The facility, which was meant to hold 250 people, was instead being occupied by more than 400 boys.
