Elon Musk and Vivek Ramaswamy's Department of Government Efficiency (DOGE) is facing legal challenges for allegedly violating the Federal Advisory Committee Act by functioning as an unauthorized federal advisory group.

While DOGE focuses on reducing federal expenditures, Bitcoin has surged to record highs, reflecting optimism in the crypto market as President Trump begins his term.
