Regulations that would block sale of older tires praised by environmental groups amid rightwing backlash

California has become the first state in the nation to mandate that replacement tires be energy efficient, a major auto industry regulation set to block the sale of older tires and make vehicles on the road greener.

State regulators have said the new rules will reduce emissions and drivers’ fuel costs. But the rules – which come as the Trump administrations fights to block other California restrictions to promote greener cars – have already sparked a rightwing backlash, with one conservative news outlet calling the policies a “massive overreach”.

DHS sent undercover agents to meetings and infiltrated chats of groups opposing Trump’s immigration crackdown

Newly disclosed records reveal the US government extensively spied on prominent leftwing organizations and on protesters as part of a vast operation into groups opposing the immigration crackdown in Minnesota earlier this year.

Internal investigative reports show the Department of Homeland Security (DHS) sent undercover agents to community meetings in the Twin Cities and New York City, infiltrated Signal chats and obtained financial records of mainstream unions and left-leaning non-profit groups.
