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."

After an expanded detention facility for child migrants reopened in Carrizo Springs, Texas, Rep. Alexandria Ocasio-Cortez, D-N.Y., tweeted Tuesday, “This is not okay, never has been okay, never will be okay - no matter the administration or party.”

In a press briefing Wednesday, Psaki attempted to cast the Biden administration’s efforts to manage immigration as a major improvement over President Donald Trump’s policies but didn’t fully address Ocasio-Cortez's criticism that such facilities shouldn’t exist at all.

Psaki said the administration had three options when it comes to child migrants: to send them back to their countries (which she said can be dangerous), to transfer them to a facility managed by the Department of Health and Human Services, or to put them in the care of families or sponsors "without any vetting." She said the administration has chosen the middle option.

“What we are doing is working as quickly as possible to process these kids into these HHS facilities, which have been revamped, which have medical and educational services available, so that we can then transfer them to families. That's what our approach is,” Psaki said.

Psaki would not commit to a request to allow media in to prove that children are treated humanely, citing privacy and security concerns. Psaki tried to explain the administration’s options in dealing with minors at the border and why the detention facilities have become a primary strategy.

“This is a difficult situation. It's a difficult choice. That's the choice we've made,” she said.

Psaki also attempted to defend delays in transferring children from facilities run by Customs and Border Protection, which often lack amenities, to Health and Human Service facilities that are intended for longer-term care. By law, children are supposed to spend no more than 72 hours in Customs and Border Protection facilities after initial apprehension.

“There were some delays last week because of weather, and because some of these facilities to safely move these kids to, did not have power and were not in a place where they could -- they had the capacity to take in these kids and do it safely. That is not our objective. That is not our goal," Psaki said. "So some, unfortunately, did stay four days, five days, or longer, but the objective is to move them as quickly as possible to the HHS sponsored facilities.”
