U.S. President Donald Trump formally signs his cabinet nominations into law during the 58th presidential inauguration in Washington, D.C. on Jan. 20. President Donald Trump vowed to bring swift change to Washington in a fiery inaugural address, yet that promise is colliding with the reality that only two members of his Cabinet cleared the Senate by the end of his first day in office.  Unlike his successors Barack Obama and George W. Bush — who each had seven of their cabinet members confirmed on Inauguration Day — Trump saw votes only for Defense Secretary James Mattis and Homeland Security Secretary John Kelly.
