Joni Ernst’s worries over President Donald Trump’s frequent trips to his Mar-a-Lago golf resort.On a conference call on Wednesday, Grassley, R-Iowa, defended the president’s visits to the Florida club.“He goes down there to have a good environment to talk to the president of China so he can get the president of China to go to intervene in the case of North Korea being a threat to the United States,” Grassley said on a conference call with Iowa reporters.
