Emily England Clyburn, the wife House majority Jim Clyburn, has died at the age of 80. They met after he was jailed in a civil rights protest and were married for nearly 60 years.

“Emily Clyburn was a champion of equality and opportunity who made a difference for countless young people in her beloved South Carolina,” House Speaker Nancy Pelosi said in a statement. “As a librarian, she intimately understood the power of learning to transform lives, and dedicated decades to ensuring that every child, servicemember, veteran and worker could access a good education that would allow him or her to climb the ladders of opportunity in America. Her extraordinary leadership, together with Jim, to increase learning opportunities at their beloved alma mater South Carolina State will stand always as an enduring tribute to her beautiful life and legacy.”

As expected, the Trump administration said on Thursday that it would revoke California’s authority to set its own vehicle emissions standards and bar states from establishing their own regulations.

The decision is likely to set off a furious legal battle.

Our message to those who claim to support states' rights is: don't trample on ours. Doing so would be an attempt to undo the progress we've made over decades. cc @EPAAWheeler #CleanerCars

Hi, @realDonaldTrump. Let me break it down in simple terms for you...

Reducing emissions:
-Protects our air & health
-Is good for the economy
-Allows families to pay less at the pump

We’re here in the 21st century. Let us know when you decide to join us. https://t.co/gZzUjXeFxo

New rule would effectively replace the Flores agreement, which sets 20-day limit for families held in custody

Eighteen (!) of the 23 (!!) prominent Democratic candidates for president are speaking at the Iowa Federation Labor Convention today.

The presidential hopefuls will address union members in Altoona, beginning at 10am ET and running, presumably, for a long time.

Some reaction to the Trump administration rule on indefinitely detaining immigrant families:

The government should NOT be jailing kids, and certainly shouldn’t be seeking to put more kids in jail for longer.

This is yet another cruel attack on children, who this administration has targeted again and again with its anti-immigrant policies.

Congress must not fund this. https://t.co/bp3uDIJder

Even a short period of detention— let alone prolonged detention—has devastating, often lifelong effects on children. https://t.co/3823D0XnhO

It's also incredibly costly. DHS declined to run the numbers in the proposed rule, so we did so for them. Each year this will cost at least $200 MILLION, and as much as over $1 BILLION.

All to hurt kids and families.https://t.co/MjsidJxQx0

Donald Trump is linking US-China trade talks with the Hong Kong protests on Twitter, suggesting that if the China government wants to work out a deal it has to “humanely” work with the protestors.

Whereas investors and foreign leaders have blamed uncertainty around trade negotiations between the US and China is triggering economic volatility around the world, Trump has insisted that negotiations between himself and China’s Xi Jinping are going well and that Jerome Powell, the chairman of the Fed chairman that Trump nominated in 2017, is to blame.

I know President Xi of China very well. He is a great leader who very much has the respect of his people. He is also a good man in a “tough business.” I have ZERO doubt that if President Xi wants to quickly and humanely solve the Hong Kong problem, he can do it. Personal meeting?

..deferral to December. It actually helps China more than us, but will be reciprocated. Millions of jobs are being lost in China to other non-Tariffed countries. Thousands of companies are leaving. Of course China wants to make a deal. Let them work humanely with Hong Kong first!
