Former Governor Terry Branstad is back in Iowa, having resigned as U.S. ambassador to China in order to campaign for President Donald Trump, Senator Joni Ernst, and other Republicans on the ballot. He’s defending Trump’s trade policy toward China, despite the impact on Iowa farmers. Speaking with reporters on October 10, Branstad “discounted polls showing President Trump and Joe Biden tied in Iowa.”

It’s a waste of time to ask any politician about polls, and Branstad has already spoken to the media at length about U.S. foreign policy toward China. Here are four more salient matters Iowa reporters could raise with the former governor.

U.S. Senator Joni Ernst told Iowa reporters in October that if articles of impeachment were referred to the Senate, she would “evaluate the facts” as a “jurist.”

Senator Chuck Grassley voted to allow deposition of witnesses in President Bill Clinton’s impeachment trial, explaining at the time he was supporting “a tightly disciplined legal process to get the information needed to help clear up important discrepancies on the record. Witnesses will not be called simply for the sake of calling witnesses. Seeking this information is important to a process that is judicious.”

Yet Iowa’s senators joined all of their Republican colleagues on January 21 to prevent senators from examining any documents the White House is withholding and from hearing any witness testimony about President Donald Trump’s conduct.
