Acquitting President Donald Trump of obstruction during his impeachment trial could reshape the power structure between the president and Congress forever, creating graver implications than the abuse-of-power claims, Sen. Angus King said. Allowing a president to thumb his nose by refusing to cooperate with a congressional investigation would set a dangerous precedent, giving the president power to operate without congressional oversight, King said. “It would be the largest transfer of power from the Congress to the executive in the history of the country,” he told The Associated Press. King, an independent from Maine, made his comments after Trump’s lawyers began his impeachment defense Saturday in the Senate.
