Biden’s transition held its weekly press briefing Wednesday, hammering home the same messaging the president-elect delivered himself earlier this week on transition delays.

The team took aim at the Department of Defense and Office of Management and Budget for their lack of cooperation in the transition and also previewed some of the “day one” policy actions Biden would take once in office.

Transition spokesperson Yohannes Abraham stressed that not working with career OMB officials is hindering and needlessly delaying the team's work on COVID-19.

“There are also health and economic repercussions to this obstruction. OMB is integral to our federal government efficiently and effectively addressing COVID,” Abraham said. “OMB leadership's refusal to fully cooperate impairs our ability to identify opportunities to maximize the relief going out to Americans during the pandemic.”

When pressed on specific types of obstruction the transition was facing, Abraham added that the DOD has not had a meeting with the transition in 11 days, following DOD’s announcement that meetings would cease over the holidays (the DOD said this was a mutual agreement, which the Biden team has denied). Abraham also said DOD held only three meetings with the Biden team after ascertainment and before the holiday break announcement.

Jen Psaki, Biden's pick for White House press secretary, also spoke of some of the policy actions Biden plans to take immediately when he takes office on Jan. 20.

She announced the Biden administration will issue a memo that halts so-called “midnight rules” from the Trump administration, citing a Department of Labor rule the Trump administration is expected to publish in January that would make it easier for businesses to classify workers as independent contractors to circumvent paying overtime, minimum-wage and other protections.

“In addition to the regulatory freeze memo, President-elect Biden has promised to rescind harmful Trump executive orders, and deliver on our promises and the promises he and Vice president-elect Harris made on the campaign trail, including by reinstating protections for dreamers, rejoining the Paris Climate Accord, or reversing President Trump's environmental rollbacks that have made our air and water dirtier and protecting and strengthening the Affordable Care Act to lower health care costs and expand access to care,” Psaki said.

The Biden transition team announced that it surpassed its goal of naming 100 staff members by the end of the year with Wednesday’s announcement that included 28 new members of the White House staff.

The staffers all will work in several key offices including the White House Presidential Personnel Office, Office of Legislative Affairs, Office of the Vice President, Office of the Staff Secretary and Oval Office Operations.

The transition team noted that the Obama-Biden 2008 transition team only had 50 staffers at this same point. Many of the new hires have ties to the Obama White House.

The transition team also said that 61% of staffers are women and 54% are people of color. Moreover, 11% of all White House staff are members of the LGBTQ+ community and almost 20% are first-generation Americans.

In a news conference Wednesday, House Speaker Nancy Pelosi, D-Calif., signaled that she’s got the votes to retain the speaker’s gavel, predicting enough Democrats will turn out for her when the new Congress convenes Sunday.

With just 222 Democrats eligible to be seated, she can only afford to lose five detractors, given a couple of vacancies and another race in New York where a winner has not yet been certified. That’s a heavy lift for Pelosi given there are still eight members in her caucus who opposed her in 2019, and two more who voted present in 2017.

Pelosi also dismissed news that Sen. Josh Hawley, R-Mo., will object to the certification of the Electoral College votes next week.

“I have no doubt that on next Wednesday, a week from today, that Joe Biden will be confirmed by the acceptance of the vote of the Electoral College as the 46th president of the United States,” she said.

On the stimulus fight, Pelosi pressured Senate Republicans to act on behalf of struggling families.

"The Democrats and Republicans in the House have passed that legislation. Who is holding up that distribution to the American people? Mitch McConnell, and the Senate Republicans," Pelosi said. "In blocking it, they are in denial of the hardship that the American people are experiencing now -- health wise, financially, in every way, their lives and livelihood in many cases are on the brink."

"This $2,000 will go a long way, not only to sustain the financial security of America's working families but will help small business to thrive as well," she added.

President Trump, who has spent a lot of time over the past week at his golf course in West Palm Beach, Florida, took to Twitter to attack Georgia Secretary of State Brad Raffensperger’s brother -- except that Raffensperger doesn’t have a brother.

In a tweet Tuesday evening just before midnight, the president called Raffensperger and Georgia’s Governor Brian Kemp a “complete disaster” as he peddled his baseless claims of election fraud.

“Now it turns out that Brad R’s brother works for China, and they definitely don’t want ‘Trump’” he wrote in a tweet. “So disgusting! #MAGA”

Trump’s tweet bolsters a popular theory in far-right conspiracy circles in recent days -- that the Georgia's secretary of state is related to a Huawei Enterprise Storage Solutions executive with the same name. Huawei has been blacklisted by the Trump administration for its ties China.

Raffensperger, however, does not have a brother. He has two sisters and neither work for Huawei.

The White House has not responded to multiple requests for comment on the tweet, and has not responded to whether the president plans to take it down, issue a correction or has apologized to the Georgia secretary of state.

Russ Vought, the current director of the Office of Management and Budget, struck back at President-elect Joe Biden's transition team one day after it leveled allegations that Trump's OMB was hindering the incoming team.

In a lengthy letter detailing what he says are a number of falsehoods, Vought wrote that Biden's team made false accusations about the OMB and said they fully participated in appropriate transition efforts -- including over 45 meetings.

"As the record shows, OMB has fully participated in appropriate transition efforts," Vought wrote. "What we have not done and will not do is use current OMB staff to write the [Biden transition team]'s legislative policy proposals to dismantle this Administration's work. OMB staff are working on this Administration's policies and will do so until this Administration's final day in office."

"Redirecting staff and resources to draft your team's budget proposals is not an OMB transition responsibility," he added.

In a weekly press conference Wednesday, Biden transition spokesman Yohannes Abraham criticized the Trump administration for failing to cooperate with their agency review teams, particularly with political leaders at OMB.

"In normal transitions -- this was the case in 2008, it was the case in 2016 -- OMB career staff provide critical analytical support to incoming administrations as they look towards the execution of their priorities and the production of their budget," Abraham said. "That analytical support has not been forthcoming from OMB. And there have been no signs that it is -- it will be forthcoming in the days to come."
