President-elect Donald Trump doesn't seem to have the support of his defense secretary nominee when it comes to scrapping the Iran nuclear deal on day one of his presidency. Retired Marine Gen. James Mattis said at his Senate confirmation hearing Thursday that while the deal is "an imperfect arms control agreement," he thinks the U.S. must uphold the deal — which Trump has dubbed "one of the dumbest deals ever."

Mattis argued the agreement, which involves the U.S. and five other countries lifting its sanctions on Iran in exchange for restrictions on its nuclear program, is integral to security in the region. "When America gives her word, we have to live up to it and work with our allies," Mattis said.

The Biden administration announced on Monday that it will grant temporary protected status to Venezuelan migrants — an action that could help an estimated 320,000 people now living in the United States.

Hundreds of thousands of Venezuelans have fled their country due to economic chaos, food and medicine shortages, and widespread and frequent power outages. Under temporary protected status, people who cannot return to their home country due to war and natural disasters are allowed to legally live and work in the U.S. Venezuelans will be able to have temporary protected status for 18 months.

The U.S. recognizes opposition leader Juan Guaido as the rightful president of Venezuela, rather than President Nicolas Maduro. In an attempt to force Maduro out, former President Donald Trump tightened sanctions against Venezuela, but did not grant temporary protected status to migrants.

"The United States is in no rush to lift sanctions," a senior Biden administration official told The Associated Press. "But we need to recognize here that unilateral sanctions over the last four years have not succeeded in achieving an electoral outcome in the country." Maduro has "adapted" to the sanctions on oil, the official added, and now is the time to "start sitting down with the international community to see how we can actually exert coordinated pressure and set clear expectations for the way forward."

The novel coronavirus that sparked the ongoing COVID-19 pandemic will continue to evolve over time, but it may be running out of the type of worrisome tricks seen in mutations first sequenced in the United Kingdom, Brazil, and South Africa, Dr. Dhruv Khullar writes in The New Yorker.

All three variants are troubling because of a change to the "spike" protein that allows the virus to latch on to humans' ACE-2 receptor and enter human cells more easily, making it more transmissible. And the Brazilian and South African variants carry an additional mutation which diminishes the ability of antibodies to bind to and neutralize the virus, possibly rendering previous infection and vaccines less effective, Khullar writes. There is good news, though — at least in the eyes of Jason McLellan, a structural biologist at the University of Texas at Austin, who believes such mutations may be few and far between going forward.

"There's just not a lot of space for the spike to continue to change in ways that allow it to evade antibodies but still bind to its receptor," McLellan told Khullar. "Substitutions that allow the virus to resist antibodies will probably also decrease its affinity for ACE-2," he continued, adding that because the variants "have independently hit on the same mutations" it's likely "we're already seeing the limits of where the virus can go."

McLellan expanded on his fairly hopeful outlook, telling Khullar that the virus will indeed keep mutating, but likely into a less lethal version. "This is what we think happened to viruses that cause the common cold," he said. "It probably caused a major illness in the past. Then it evolved to a place where it's less deadly."

Former President Donald Trump spent much of 2020 pushing unfounded claims of voter fraud, often pinpointing mail-in voting as a major culprit. Yet, he continues to do it himself.

Trump, now a Palm Beach, Florida, resident, requested a mail ballot on Friday so he can vote in the city's municipal elections, The Palm Beach Post reports. Trump did vote in person in November's general election, but he previously cast mail ballots while in the White House, praising Florida's security while simultaneously criticizing the system at large.

At the time, he claimed he was he was too busy to leave Washington, and he also repeatedly drew a distinction between absentee ballots and universal vote-by-mail. But that doesn't seem to apply in this case. Read more at The Palm Beach Post. Tim O'Donnell

The Tax Policy Center broke down how the Democrats COVID-19 relief bill, which will likely be signed into law this week by President Biden, will affect Americans across income brackets in one easy-to-read chart on Monday.

In its analysis, TPC compared the American Rescue Plan's expected tax relief to that of the 2017 Republican-led Tax Cuts and Jobs Act, which also passed through the Senate along party lines with a simple majority vote thanks to a procedural tool called budget reconciliation. This time around, the vast majority — nearly 70 percent — of the tax benefits from the ARP will go to low- and moderate-income households, which includes those making $91,000 per year or less. Nearly half of the TCJA cuts, on the other hand, went to the top 5 percent of earners, which that year included those who made more than $308,000.

Overall, the ARP's $3,000 average tax benefit is almost double the average tax cut from the TCJA, in large part because of the next round of stimulus checks that will be sent directly to individuals, which the TPC analysis says will trim household taxes by about $2,300.

The former CEO of Papa John's is assuring the public he's been working on not using racist language, an effort that has apparently been ongoing for nearly two years.

John Schnatter, the Papa John's founder who in 2018 stepped down as chairman after admitting he used the N-word during a conference call, told One America News Network the pizza chain's board has painted him "as a racist" when "they know he's not a racist," per Mediaite. From there, Schnatter described his "goals," evidently including no longer saying racial slurs.

"We've had three goals for the last 20 months," Schnatter said. "To get rid of this N-word in my vocabulary and dictionary and everything else, because it's just not true, figure out how they did this, and get on with my life."

The former pizza boss also told OANN he "used to lay in bed" after his ouster wondering "how did they do this," and he called on Papa John's to come out and declare that it "didn't follow proper due diligence" and that he actually "has no history of racism."

Schnatter stepped down as Papa John's chair after Forbes reported that he "used the N-word on a conference call" that had been "designed as a role-playing exercise for Schnatter in an effort to prevent future public-relations snafus." He apologized at the time, saying "racism has no place in our society." Shortly after, though, Schnatter said he resigned because the board asked him to "without apparently doing any investigation" and that he now regrets doing so.

Later, Schnatter would vow that a "day of reckoning" would come in a bizarre 2019 interview, in which he also famously declared he's eaten "over 40 pizzas in the last 30 days."

Update: In a statement on Monday, Schnatter said he has been seeking to eliminate "false perceptions in the media" and that "on OANN, I tried to say, 'Get rid of this n-word in (the) vocabulary and dictionary (of the news media), and everything else because it's just not true,' – reflecting my commitment to correct the false and malicious reporting by the news media about the conference call."

More than 1,000 worker deaths from COVID-19 that were linked to workplace transmission were never investigated by the Occupational Safety and Health Administration at the state or local level, a Wall Street Journal investigation found. The Journal notes that the number likely understates that actual toll.

Many of those fatalities weren't reported to OSHA agencies by employers in the first place, but David Michaels, the OSHA director in the Obama administration, told the Journal the coronavirus pandemic still "exposed OSHA's great weaknesses."

Indeed, the Journal reports, OSHA records and state health care data show the agencies often took limited steps when they did respond to safety complaints. For example, the Journal identified 180 COVID-19 deaths among workers that occurred four weeks or more after complaints to OSHA agencies. In those cases, the investigation didn't extend beyond corresponding with employers. And despite an increase in complaints during the pandemic, OSHA agencies actually conducted fewer inspections than they did in the previous year.

But, aside from a lack of action, it seems there were also built-in inefficiencies that left the OSHA unprepared to respond to pandemic. The agency's rules, the Journal reports, are "designed to minimize chemical-exposure risks and injuries such as falls and electric shocks," not infectious disease. Officials did start drafting rules centered on preventing the spread of such diseases in healthcare facilities after the 2009 H1N1 flu pandemic, but never completed the process.
