The Trump administration officially rolled back Biden-era fuel-efficiency standards on Monday, reducing the 2031 target for the U.S. vehicle fleet by about 15 miles per gallon. The administration says updated rules will lower vehicle prices by about $1,300 on average, while opponents argue drivers will spend more on gasoline. The change reverses a key part of Former President Biden’s push to shift the market from gas-powered vehicles toward electric vehicles (EVs), following President Trump’s earlier revocation of Biden’s nonbinding goal for EVs to comprise half of new-car sales by 2030. The newsletter also reports that the United States and China agreed to cut tariffs on $60 billion of goods, extend their trade truce through Jan. 10 and discuss artificial intelligence risks. The Iran war reached seven months after Trump rejected a seven-day Iranian ceasefire proposal, while Senate opposition complicated Sean Parnell’s potential nomination as Army secretary. The Senate was expected to vote on a bipartisan college-sports bill covering athlete compensation, transfers, scholarships, medical coverage and NCAA antitrust protections.
