Senate Republicans say upcoming hearings will provide thorough oversight of President Trump’s use of executive power. Senate Majority Leader John Thune (R-S.D.) says he;s observed a lot of presidents and says they all try to exert as much executive power as they can. Then he says as a matter of course those decisions often have to face scutiny from the courts and Congress, Thune  told CNN Republican senators “have a responsibility as an independent, coequal branch of the government to make sure that we’re doing appropriate oversight of these decisions.”
