Biden has yet to hold a formal press conference 45 days into his administration, despite 15 of his predecessors having done so within that time frame.

When asked about the delay, White House press secretary Jen Psaki said a press conference would be held  “before the end of the month” and argued Biden’s focus was on the country.

Senate Democrats have hit a snag early in the marathon voting session on the $1.9 trillion coronavirus relief legislation, as moderate Democrat Sen. Joe Manchin, W.Va., threatens to unravel an emerging agreement on how to handle jobless benefits in the package.

Democrats on Friday unveiled what they thought was an agreement on unemployment insurance, sponsored by Sen. Tom Carper, D-Del., that would cut the weekly jobless benefit from the $400 allotment in the House bill to $300, while allowing the benefit to continue through September rather than through August. The agreement also included the first $10,200 paid out through the unemployment program being untaxed.

But Manchin, who has been urging his colleagues and the White House to further target the bill, isn't sold on the Carper proposal.

Further complicating matters for Democrats is an amendment expected from Sen. Rob Portman, R-Ohio, which would slim down the jobless benefits even more. Portman's proposal would also cut the weekly benefit to $300 dollars, but it would end the program in July, potentially appealing to Manchin.

The Senate was at a standstill as Democrats worked to smooth out the kinks.

White House press secretary Jen Psaki said during a press briefing Friday that Biden was “deeply engaged” in getting the American Rescue Plan across the finish line and took “nothing for granted.”

"I fully expect him to be on the phone through the weekend with Democrats and Republicans as needed, answering questions, addressing needs," Psaki said.

When pressed on how big of a priority it was to get a Republican on board, Psaki demurred, arguing that there was bipartisan support outside of Washington.

Psaki also declined to say what the next legislative focus would be, despite Biden’s continued Oval Office meetings with bipartisan members of Congress on the issue of infrastructure, which many expect to be his next on his legislative agenda.

White House press secretary Jen Psaki was asked during a press briefing Friday several rounds of questions focused on the growing number of migrant children coming to the U.S. southern border.

She was asked specifically if the president felt his rhetoric on the campaign trail had contributed to the current spike in activity.

Psaki stressed the administration has sought to clarify that "this is not the time to come," but said by virtue of taking a different approach and allowing unaccompanied minors to stay, it “mathematically” makes sense that there would be an increase.

Despite the increase, Psaki unequivocally said the administration was not rethinking its policy when it comes to unaccompanied minors at the border.

"I think this issue requires us taking a step back as human beings and as mothers, of which I am one," Psaki said.

"They go through the processing system that everyone goes through, but we want to ensure that that is done by treating them humanely and with respect," Pskai said. "Many of them will be sent back home eventually, but we are talking about how we treat them as they come in the country."

Earlier in the day, House Minority Leader Kevin McCarthy sent a letter to Biden expressing "great concern" with the administration's approach to the "crisis" at the border and requested a meeting with the president on the issue.
