Senate Majority Leader Chuck Schumer, in a remarkably candid moment, told reporters that during a closed-door lunch with his caucus Tuesday, he made a strong pitch for them to set aside differences over specific policies like the minimum wage hike and just vote for the president's COVID-19 relief bill.

Sen. Dick Durbin, D-Ill., then went a bit further after Schumer left the room and said the majority leader had "begged" his members to drop their opposition, emphasizing that the relief bill is Biden's signature legislation, and they need to stick together.

"He's begging all of us -- despite disagreements people may have -- this is the Administration's signature bill...And we need to stick together," Durbin recounted.

Some moderate Democrats like Sens. Joe Manchin, D-W.V., and Kyrsten Sinema, D-Ariz., have expressed concern about a $15 per hour minimum wage hike included in $1.9 trillion relief proposal. Manchin said an $11 an hour increase would be more appropriate for his state.

Republicans have hammered Democrats for forcing the increase on businesses suffering under the economic strains of the pandemic, but supporters of the wage increase -- a doubling of the current federal minimum wage -- note that the Biden plan is implemented over a five-year period.

GOP Sens. Tom Cotton of Arkansas and Utah's Mitt Romney introduced a plan Tuesday that would increase the minimum wage to $10 per hour by 2025 with a mandatory requirement that businesses implement E-Verify to ensure undocumented workers do not receive the increase.

The GOP proposal is not expected to be adopted as Democrats speed toward passage of the overall Biden plan.

The Senate has confirmed Tom Vilsack to serve as secretary of agriculture, in a 92-7 vote.

Sen. Bernie Sanders voted with six Republicans against Vilsack, who had the same role under former President Barack Obama.

A spokesperson for Republican Leader Mitch McConnell confirmed reports to ABC News that McConnell intends to support the nomination of Merrick Garland to serve as attorney general.

McConnell's support for Garland was first reported by Politico.

The Senate Judiciary Committee on Tuesday wrapped up two days of hearings on Garland's nomination. The committee is scheduled to hold a vote on the nomination on March 1.

McConnell's support for Garland is in stark contrast to his 2016 efforts that successfully kept Garland from the Supreme Court bench.

Senate Minority Leader Mitch McConnell doubled down on his position that the COVID-19 proposal from Democrats is far too large, not targeted enough and flies in the face of bipartisanship during a press conference Tuesday.

"We think this is dramatically more money than is required at this particular juncture. It also includes a number of things that have absolutely nothing to do with COVID relief," McConnel said. "And so it will be controversial."

McConnell said his conference is united Tuesday in "opposition to what the Biden administration is trying to do," arguing that Biden, who campaigned as a moderate, has been pushing far-left policies since his administration began, calling Biden's "a totally partisan approach to COVID relief."

The White House was surprised to discover that Johnson & Johnson will only have about 3 to 4 million doses of its vaccine ready to ship once the FDA grants an emergency use authorization, White House press secretary Jen Psaki said during a press briefing Wednesday.

Johnson & Johnson had estimated it could ship 12 million doses at the end of February in a $1 billion contract signed with the federal government in August.

“We were surprised to learn that Johnson & Johnson was behind on their manufacturing. As you noted, it was kind of reported earlier to be about 10 million, and now it's more like 3 to 4 million doses that they would be ready to ship next week if they are moved through the FDA process, which is not yet concluded, just to note," Psaki said. "And we are going to continue to work with them on ensuring that that can be expedited.”

Despite the initial availability, Johnson & Johnson has said it expects 20 million doses to be available by the end of March and to meet its contractual obligation for 100 million doses by the end of June.
