On Thursday, President Joe Biden announced that all passengers must show proof of a negative COVID-19 test within one day of flying into the U.S., regardless of their vaccination status or nationality.

ABC News' chief medical correspondent, Dr. Jennifer Ashton, told David Muir on Thursday that vaccinations remain the most important tool we have in combatting COVID-19 this winter."Some protection is better than none, and while we learn about the many mutations that omicron has ... we have to double down on what we know is going to be our best tool in the toolbox, and that is vaccination," Ashton said.

Regarding boosters, Fauci has urged Americans who are eligible toget the shot now."Right now, I would not be waiting," he said Wednesday."People say, well, if we're going to have a booster-specific vaccine, should we wait? If you are eligible, namely six months with a double mRNA dose, or two months with the J&J, get boosted now."

"We may not need a variant-specific boost," he added.

US Employers Added Sluggish 210,000 Jobs In NovemberThat's after adding more than half a million jobs in October. So we don’t need a trillion $ bill to juice the economy, since it’s doing so well.. 'sluggish', despite that unemployment is lower than expected. This number will be revised up just like the last few months were. I don't think this report is as bad as it looks if you dive into it. Plus unemployment rate still ticked down. There is a ways to go but I think we're still on the right track!
