Google illegally fired two employees involved in labor organizing last year, the National Labor Relations Board alleged in a complaint on Wednesday.

The Department of Transportation said Wednesday it will no longer require airlines to make the same accommodations for emotional support animals as they do for trained service dogs. No more guaranteed free flights for comfort cats and dogs, therapy monkeys or miniature horse companions.

A service dog is trained to do work or perform a task to benefit an individual with a disability. Emotional support and psychiatric service animals function therapeutically. And starting in 2021, it will be up to individual airlines to decide whether or not treat the two the same.

President Trump is threatening to veto a critical defense spending bill unless Congress agrees to repeal a liability shield for social media companies.

The president tweeted late Tuesday that Section 230 of the 1996 Communications Decency Act is "a serious threat to our National Security & Election Integrity."

Section 230 provides legal protection for technology companies over content from third parties and users. Trump referred to the provision as a "liability shielding gift" to "Big Tech."

The eldest granddaughter of President-elect Joe Biden, Naomi Biden, joked to her 188,000 Twitter followers that she couldn't stop watching cable news and that she'd "kill to be one of those people who 'can't eat when they're stressed' right about now."

The Arecibo Observatory in Puerto Rico has collapsed, after weeks of concern from scientists over the fate of what was once the world's largest single-dish radio telescope. Arecibo's 900-ton equipment platform, suspended 500 feet above the dish, fell overnight after the last of its healthy support cables failed to keep it in place.

No injuries were reported, according to the National Science Foundation, which oversees the renowned research facility.
