President Donald Trump’s fight with California over vehicle greenhouse gas emissions appears destined to become a long court battle, with California and at least one other state vowing Wednesday to sue to sustain the state’s nearly 50-year-old authority to set its own standards.

One day after his EPA administrator vowed to revoke in “the very near future” a waiver that allows California to set stricter mileage standards than the federal government, Trump made the announcement via a series of tweets.

A three-judge panel on the 5th U.S. Circuit Court of Appeals suggested during a Tuesday hearing it might uphold at least part of a lower court ruling to strike down the 2010 health care law.

Two judges, both appointed by Republican presidents, questioned the constitutionality of the law’s requirement that most Americans get health care coverage. A third, appointed by Democratic President Jimmy Carter, stayed silent throughout the nearly two-hour oral argument hearing in New Orleans, which follows a December decision by federal Judge Reed O’Connor of the Northern District of Texas calling for the law to be struck down.

Blue states and green groups are gearing up to sue the Trump administration over its new carbon emissions rule finalized Wednesday, which critics say fails to address climate change and the public health risks associated with pollution from the power sector.

The EPA’s Affordable Clean Energy rule rescinds the Obama administration’s ambitious Clean Power Plan and replaces it with less stringent guidelines for states and coal-fired power plants to reduce their emissions.

Several abortion-rights and LGBT advocacy groups announced Tuesday that they filed the fourth major lawsuit challenging a Trump administration rule that could affect access to abortion and contraception.

The challenge comes a week after state attorneys general filed different lawsuits also attempting to block the final rule from going into effect this year.

Former Gov. Jerry Brown signed it almost a year ago, but it’s still unclear what California’s first-in-the-nation data privacy law will look like in practice. 

The law was the first in the United States to attempt to define internet users’ rights over their personal data that companies often sell for marketing purposes. But ahead of the law’s Jan. 1, 2020, implementation date, the state is still grappling with the balance between consumer protection and a light regulatory approach that has allowed the tech sector to become a major part of the California economy.

Updated 6:08 p.m. | Senate Minority Leader Charles E. Schumer on Wednesday said Democrats would propose an amendment to a $13.45 billion disaster aid package that would block the Justice Department from carrying out President Donald Trump’s push for a court ruling invalidating the 2010 health care law.

The move is another threat to consensus on a supplemental spending bill that leaders hoped could be negotiated in a bipartisan manner, but talks have until now been weighed down by disagreement over the package’s size and scope. Senate Democrats’ strategy introduces a new hurdle and is part of a broader push by Democrats to steer public attention toward health care.

Democrats are seeking to move beyond special counsel Robert S. Mueller III’s report to a different action taken this week by the Justice Department: its statement supporting Texas’ legal challenge to the 2010 health care law, which said the entire act should fall.

House Democrats, highlighting the differences between their positions and the administration’s, unveiled draft legislation Tuesday that seeks to lower health care costs for people who get insurance coverage through the federal and state marketplaces.

Lawmakers want to pass a federal data privacy bill before 2020 to put Washington on par with Europe and ahead of several U.S. states. But those efforts could be delayed because of differences between technology companies and Congress over how powerful the law should be and how it should be structured.

A delay in enacting a uniform federal law could leave technology giants and startup app makers trying to meet a latticework of standards set by multiple regulations passed by many states as well as a growing international set of rules being modeled after the European Union’s General Data Protection Regulation, or GDPR. Companies also could be liable for fines and face consumer lawsuits allowed by state laws.

Fresh off her 2018 gubernatorial loss and ahead of a possible 2020 Senate bid, Georgia Democrat Stacey Abrams will be giving the party’s response to President Donald Trump’s State of the Union address next week.

Senate Minority Leader Charles E. Schumer, D-N.Y., announced the selection Tuesday, a week before the address, which had been delayed in the fight over the partial government shutdown. 

A longtime aide to Sen. Kamala Harris resigned Wednesday after another news publication asked about a $400,000 sexual harassment and retaliation settlement stemming from his time working for the California Department of Justice.
