Ivanka Trump was due to attend three campaign events in Georgia Monday for GOP Sens. David Perdue and Kelly Loeffler, but she tweeted that two of them will be postponed due to Congress voting on the pandemic relief bill.

All eyes are on the Georgia Senate runoffs, as the outcomes will decide which party has control of the Senate. Vice President-elect Kamala Harris is currently scheduled to campaign in Georgia for the Democratic candidates on Monday.

President-elect Biden and Vice President-elect Harris announced new members of their National Economic Council on Monday morning in a press release, expanding the group that will work alongside Brian Deese and other forthcoming staff.

Biden and Harris appointed Joelle Gample as the Special Assistant to the President for Economic Policy. They also selected David Kamin as the Deputy Director for the National Economic Council and Bharat Ramamurti as the Deputy Director for the National Economic Council for Financial Reform and Consumer Protection.

Kamin previously joins the long list of Obama White House alumni returning to a Biden administration. He previously served as Special Assistant to the President for Economic Policy and also worked as special assistant, and later adviser, to the Director of the Office of Management and Budget.

Ramamurti comes to Biden’s administration with ties to Sen. Elizabeth Warren. He served as an economic adviser to Warren during her 2020 presidential campaign and senior counsel for banking and economic policy in her Senate office.

Treasury Secretary Steve Mnuchin said Monday that if the pandemic relief bill becomes law, direct deposits to Americans could start by the beginning of next week.

“We will be sending out next week direct deposit,” Mnuchin said in a phone interview with CNBC Monday about the hard-fought political compromise that's dominating the political scene on Capitol Hill. “I expect we’ll get the money out by the beginning of next week.”

“People are going see this money the beginning of next week,” he added.

Mnuchin also spoke approvingly of the deal that was made to get the bill over the finish line.

“This overall bill I think is fabulous,” he said, adding that, "this is a large bill and has a little bit of everything in it for everybody."

Finally, Mnuchin also addressed the suspected Russian cyber hack of U.S government agencies and Fortune 500 companies, saying, “there’s been no damage, nor have we seen any large amounts of information displaced” after the cyber attack into the Treasury Department’s unclassified systems.

President-elect Joe Biden is expected to receive a coronavirus vaccine Monday afternoon on camera, a move that many hope will stoke public confidence in the shot and also ensure the continuity of government.

Meanwhile, Vice President-elect Kamala Harris will be in Georgia campaigning Monday as the Senate runoff races that will decide which party controls the Senate heats up. Harris currently has an event scheduled for 1 p.m. in Columbus.

On Capitol Hill Monday, lawmakers are expected to finally vote on a stimulus deal. After weekend negotiations, congressional leaders signaled Sunday evening that they had reached a deal. The new bill is expected to include revamped unemployment benefits and aid for hard-hit small businesses.

President Donald Trump, meanwhile, has tweeted that “big news” is coming out of Pennsylvania. The Trump campaign is expected to unveil new legal action with the U.S. Supreme Court surrounding Pennsylvania’s election results as part of his ongoing efforts to undermine the election.

In a virtual hearing on elections before the Georgia state House Governmental Affairs Committee, Secretary of State Brad Raffensperger said for the first time that he supports changing state law so that voters must have an excuse to request an absentee ballot.

The Georgia Senate Republican Caucus called for this in a Dec. 8 statement.

"This cycle has shown, we need to move to an excuse-based system for absentee voting. The no-excuses system voted into law in 2005 -- long before most of you, if not all of you, long before I was in the General Assembly -- it makes no sense when we have three weeks of in-person, early voting available. It opens the door to potential illegal voting," Raffensperger said.

As the secretary noted in his remarks, no excuse absentee voting has been legal in Georgia since 2005 -- so this would be a significant change.

As he has done before, he also advocated for a change in the state law to require voters have ID -- as opposed to signature matching -- for requesting and submitting absentee ballots.

Despite calling for these changes -- and despite saying there are "real substantive questions" about the election -- Raffensperger still maintained that "the vast majority of claims we have seen online and in the media, and even discussed in the halls of the Capitol are simply unfounded," going on to note that far-right news organizations are issuing retractions over their coverage.
