President Trump on Wednesday suggested that he might not accept the election results if he is not declared the winner in November, in response to a reporter's question about whether he would commit to a peaceful transfer of power — regardless of the outcome of the election.

California will phase out the sale of all gasoline-powered vehicles by 2035 in a bid to lead the U.S. in reducing greenhouse gas emissions by encouraging the state's drivers to switch to electric cars.

Gov. Gavin Newsom signed an executive order Wednesday that amounts to the most aggressive clean-car policy in the United States. Although it bans the sale of new gas cars and trucks after the 15-year deadline, it will still allow such vehicles to be owned and sold on the used-car market.

President Trump on Wednesday decried reported health agency efforts to issue stricter guidelines for evaluating a vaccine against COVID-19, accusing the Food and Drug Administration of playing politics.

Trump was apparently reacting to a Tuesday report in the New York Times that said the agency will soon move to tighten requirements for emergency authorization of any coronavirus vaccine to better ensure its safety and effectiveness.

When President Trump and Democratic presidential nominee Joe Biden face off Tuesday night in the first presidential debate, there's one topic they're not expected to get asked about: climate.

Thirty-six senators, spearheaded by Ed Markey, D-Mass., signed a letter to the Commission on Presidential Debates, urging that climate change receive more attention.

Voters in a number of swing states this November will have more leeway in getting their mail ballots back in time to count, should rule changes announced in the past week hold up to legal challenges. But the changes could delay the reporting of election results and possibly set up court fights down the line.

In a new court filing, TikTok leaders make clear just how much is at stake in a prolonged battle with the Trump administration: If TikTok were banned for two months, up to half of its users in America would never come back. If the ban persisted for six months, 90% of TikTok users would be gone forever, according to a top TikTok executive.

Jean lost her job as a school bus driver in Chicago during the pandemic. She was managing OK with unemployment money. But then, about two weeks ago, she got a desperate call from her adult son.

"His job had laid him off, and he wasn't able to pay rent," she says. There was an eviction moratorium in Chicago, but Jean says the landlord wanted her son out anyway.

She says the landlord got someone to threaten her son, and to shoot his dog — a German shepherd mix he'd had for years.

President Trump warned tech companies he is "watching them very closely during this election cycle" as his administration proposed stripping online platforms of long-held legal protections.

"We see so many things that are unfair," Trump said during at a White House discussion with Republican state attorneys general about social media. "It's very serious. Very bad. Very serious."

Gale Sayers, a graceful and quick Chicago Bears running back whose elusiveness bedeviled defenses and delighted fans, has died, the team and the NFL announced Wednesday. He was 77.

Sayers was a fearsome competitor, but he was also famous for his character and fortitude.

The story of the Black football star's friendship with a white teammate, Brian Piccolo, inspired the beloved 1971 TV movie Brian's Song, after Sayers used his acceptance speech for the NFL's Most Courageous Player award to praise his less-heralded friend who was battling cancer.

"Plucky" is one of those words that doesn't get out and about much anymore.

Something about it feels off, a bit — regressive, condescending, even vaguely sexist, as it's usually only seen in the company of the word "heroine" these days.

There's this one story, in a new book by comic artist Allie Brosh, where four guys dress a dog in a humiliating costume and parade him down Las Vegas Boulevard — all to celebrate some human's birthday. Needless to say, the dog is confused, and overwhelmed.

Sometimes humans struggle to find the words to convey the sheer depth of their love for one another. Leave it to Sam McBratney's Little Nutbrown Hare and Big Nutbrown Hare in Guess How Much I Love You to show us the way.

They love each other as high as they can hop, they love each other across the river and over the hills, and finally, all the way up to the sky.

McBratney died at his home in County Antrim, Northern Ireland surrounded by family on September 18, according to his publisher, Walker Books. He was 77. No cause of death was given.

The writer Laila Lalami is originally from Morocco. She moved to California as a grad student.

She thought when she finished school, she'd go home. But then she fell in love with — and married — an American. His parents were Cuban immigrants.

Lalami writes about what it means for her to be an American citizen in her new book, Conditional Citizens; by her definition those are citizens who are sometimes embraced by America, and sometimes rejected.
