Biden's 1st 100 days live updates: Senate passes COVID relief bill along party lines

President Joe Biden is expected to announce a major partnership Tuesday afternoon between pharmaceutical giants Merck & Co. and Johnson & Johnson to help produce J&J's single-shot vaccine, a White House official confirms to ABC News. The move, first reported by the Washington Post, will help increase vaccine supply of the single-shot vaccine.

The FDA approved an Emergency Use Authorization for the vaccine Saturday, which triggered the shipment of nearly 3.9 million doses of the vaccine. Of those, 800,000 are expected to go directly to pharmacies.

As the COVID-19 relief debate moves forward in the Senate, Sen. Susan Collins, R-Maine, said Monday night that she is "increasingly convinced" there won't be a compromise on a relief bill.

"I'm becoming increasingly convinced that, regrettably, there is not as much interest as that I would like to see on the Democratic side of the aisle and the White House in trying to come to a compromise," Collins said. "And I don't understand how the White House can describe a bill that passed the House without a single Republican vote as being bipartisan -- what was bipartisan was the opposition to the bill." 

Collins was part of a bipartisan group that helped move the last COVID-19 relief bill through the Senate. But now, Collins said it's "up to Chuck Schumer and the White House whether they are interested in trying to gain some Republican support or not." 

Collins said Democrats are being similarly uncompromising on the minimum wage, which they would like raised to $15. 

"The minimum wage could be brought to the floor as a separate bill and I believe that a $10 minimum wage would pass," Collins said. "That would make life so much better for so many low-income workers and yet the approach that's been taken is all or nothing on 15. I don't understand that."

Sen. Mitt Romney returned to the Capitol Monday with a black eye. When reporters asked what happened, he joked that he went to the Conservative Political Action Conference in Orlando, Florida, where former President Donald Trump and other conservative opponents had gathered this weekend.

"Yeah, I had kind of a tough, tough weekend," he said. "You see that? Look at what I got. I went to CPAC, that was a problem."

In reality, he said he took a fall and was knocked unconscious while he was in Boston with his grandchildren. He was taken to the hospital and given "a lot of stitches" through his eyebrow and lip.
