By Chris Kaegard As Republican presidential candidate Donald Trump's feud with the parents of fallen soldier Humayun Khan neared the start of its second week, the Democrat challenging U.S. Rep. Darin LaHood called on the first-term lawmaker to repudiate Trump's comments and rescind his support of the GOP nominee. LaHood's campaign, in turn, reaffirmed in a statement a stance he has previously taken against "divisive rhetoric" without referencing Trump's specific remarks. Noting that "there are many Republicans, people of good faith, people of good nature, who have started to move away from the Trump campaign," Junius Rodriguez, a professor at Eureka College and self-described conservative Democrat, raised the issue during a campaign appearance outside of the GAR Hall on Wednesday. "Anyone who seeks or holds public office must understand that there is a point when country must take precedence over political partisanship," he said. Rodriguez ticked off a list of groups or individuals Trump had aimed barbs at, and called it "inexcusable" behavior. "When is enough, enough?" he asked. "At what point do the American people say we're going to turn our back on someone who represents these base elements of American society? This is not who we are as a nation. I think any time you have a sitting congressman, sitting in the House of Representatives, who says, 'I can endorse this person' … you need to re-evaluate where is your moral center." In a statement expressing support for military members and their families, LaHood campaign spokesman Jim Reis said the congressman "will not engage in political demagoguery and use the sacrifices of our nation's heroes to make political points in this campaign. … Congressman LaHood has said repeatedly and on the record that he disavows racist, sexist, and any otherwise divisive rhetoric no matter which candidate it comes from." Reis also said that LaHood had made a commitment to support whomever won the GOP nomination.
