Upon taking office, senators-elect must swear or affirm that they will support and defend the Constitution. The president of the Senate or a surrogate administers the oath to newly elected or re-elected senators. The oath is required by the Constitution; the wording is prescribed by law.
Sen. Chuck Grassley has taken this oath seven times, Sen. Joni Ernst one time. By supporting President Donald Trump’s reallocation of funds set by Congress, they have violated their oath.
Citizens of Iowa, please let them know you care.
