Republicans are analyzing the financial implications of Donald Trump's proposed tax cuts following his election victory. The cost of preserving the current tax system is high, and lawmakers and advisers are unsure how much money can be allocated to further tax cuts. Trump has shifted his focus to filling positions in his new administration, with Susie Wiles becoming the first woman to hold the title of White House chief of staff. Meanwhile, President Biden has urged Americans to accept Trump's election and Democrats are struggling to explain Vice President Kamala Harris's defeat.
